I find that the drag and drop experience can quickly become a nightmare, especially on mobile. To tap, hold, drag, and scroll, all at the same time, is both difficult to achieve, and prone to errors. I've always had in mind this 2-step approach, where picking an element and placing it were two separate steps. So I implemented this basic version to showcase my idea.
While it might take more time than a regular drag and drop, the benefit is for people who struggle with holding down the mouse button. With picknplace.js, you only need two clicks and some scrolling.
This solution is meant as an experiment, so I'm open to discussion.
This has the effect that you’re shifting the list rather than the item. And yet your actual controls are anchored to the item. On a touch device, to shift an item from the middle of a list to the top: • With traditional drag-and-drop: press in the middle (long press or regular press on a movement grabby), drag upwards, release. • With this: tap in the middle, on the item, then press anywhere, drag down, release. It’s uncomfortable. The logical entity you’re manipulating is the item, but you’re having to do it by interacting with the list, and if your drag starts on the item it’ll achieve the opposite of what you want. Brilliant! Its been a while since I've seen a brand new UX patten. As some others have mentioned, the picked state needs to be a bit more clear. Some suggestions - 1. As a border around 'Pick' to indicate it as an action 2. Once an item is picked, add a mask on the whole page, with only the picked item in front of the mask. (This is going to be a bit challenging, I'm guessing, to show the gaps between the items as you scroll) 3. Once an item is picked, the 'Cancel' and 'Place' bar should have a background. Sometimes this overlaps the list and is not clearly visible. 4. It should not be possible to scroll way above or below the list. 5. On 'Cancel' scroll back to the item. Again, congratulations! It's one thing to think of something, quite another to be able to implement it nicely. +1 inspiring and relevant to a project i am working on. I would suggest having the place button next to/in the item being dragged like Pick. When learning to use this, having it at a distance creates unnecessary cognitive burden. Also, I would probably make the entire item clickable for pick, if there didn’t have to be a click target on the item for other functionality. Yes! This is very cool. Should be somewhat “locked” into the right area of scroll and picked item should have some height above the others. I also hate drag and drop. It'd be good if when you picked something it automatically added the border too - otherwise I think this won't work on short pages? I have some hesitations though - relying on scroll as the positioning method means that if you don't have a fine-grained scroll method e.g. on desktop, if you have a non-continuous wheel, you'll need to rely on "drag and dropping" the scroll bar, which doesn't really improve things (and has its own issues if your page is very long). I think I'd prefer something other than scroll-to-position. Like what about making gaps between items with a "drop" button? Or adding up/down arrow buttons to the "picked" element so that fine grained adjustments could be done? This looks like an interesting concept! > I find that the drag and drop experience can quickly become a nightmare, especially on mobile. To me, drag and drop is only a nightmare on mobile. On desktop (using a mouse or trackpad), drag and drop actually works quite well. Your design experiment reminds me of a recent talk of Scott Jenson, where he talked about how we just took over established UX patterns from desktop to mobile as is, and how that created all sorts of nuisances. (https://youtu.be/1fZTOjd_bOQ?t=1565) If mobile drag&drop was implemented like you are suggesting from the very start, I actually might have preferred that over the situation we now ended up with. One technical note on your implementation: on certain mobile browsers, there is a glitch where the UI can jump around as the browser dynamically slides top or bottom menu bars in and out. > On desktop (using a mouse or trackpad), drag and drop actually works quite well. Strong disagree here. It is intuitive, it is easy to demonstrate. But it's not really convenient, especially on a trackpad. I have enough mouse agility to play RTS games but not to do a reliable drag-and-drop, especially in a complicated case - across windows, with scroll, etc. On macOS, I find “3 finger drag” very convenient to use, and for me it works a lot better than “press and hold”. (https://support.apple.com/en-us/102341) It even allows you to briefly lift your fingers to reposition them on the trackpad without stopping the drag action. Yes, it can get tricky if you have to scroll a bunch, e.g. moving a file in a big directory into a subfolder, trying to hit that one pixel where it will scroll up, or using two other fingers to attempt to scroll, while holding the drag finger down...(CLI pros, you win this one). I would like a desktop pick and place that works like drag and drop, you click and then it sticks to the cursor, but you are free to do whatever gestures until you click again. > while holding the drag finger down I'm not sure if this is common on other desktop operating systems but the 'Drag Lock' feature on macOS allows you to double-tap an item, then drag it without holding the button down to begin a drag. At that point lifting your finger continues the drag until you tap once to release it. I would be amazed at how many people using macOS have never found this option except I'm not sure I've ever seen it being called out as a feature, and nowadays it's also buried deep under Accessibility settings (the irony) instead of just being a Trackpad option, so a lot of users might not even think to go there. Double tap or double click is to open a file. If you're using it to do anything else, that's so counter intuitive. I never said it was intuitive, only that it exists ;) I’d argue that double-click to open a file is also not intuitive, but it is now the expected behaviour. Documents don’t have to be touched twice in real life to have them open and reveal their secrets. Plus, I do use Drag Lock, so that behaviour now does feel intuitive to me. There’s a lot to be said for what is effectively learned behaviour in intuition. This is really nice and a very original take. It feels good on mobile / other touch devices. I'd love to see it feel a bit more polished on desktop (maybe I'll give that a shot if I find a bit of spare time!) - I could see a few simple things like adding up/down arrows to the picked item and wiring into up and down arrow presses going a long way to making it work really well there too. Genuinely, thank you for sharing this, it's something different and interesting. I did not like this as is and found it confusing, but think it has potential and with a few adjustments could be great. I am sure you might have been planning them, and so congratulations on getting something out for comment rather than over building. 1. It will be more intuitive if you can long press or click on the item rather than have to click the "pick" link. That behavior is too deeply ingrained from drag and drop at this point. 2. It would help to show place locations where it will be inserted between objects. I found myself instinctively scrolling up and down to line it up perfectly because it just didnt feel likely to succeed if it wasnt properly placed in the middle, and the absence of visual cues make it seem like I needed to me more accurate with my placement. Overall cool concept and good work. Keep it up. Great work building something and having the courage to show HN ;-) Interesting design. Even though I read the instructions still could not get it to work for 30 or so seconds. Might want to show some text 'Now Scroll' with up/down arrows to the left or right of the list. Seems ok when the list is in the middle of the page and you already have room to scroll up and down, but how is it going to work when the list is at the top or bottom of the page? Or when the page is so short it does not scroll at all? I suppose you could have the container scroll but then it needs to be considerable larger than the list. Honestly when you click 'Pick' all of the others should say 'Place' would be more intuitive and give the user options to support both.
As they use it they will pick up they can scroll if they want. This is awesome. I wonder how it would feel if just the selections scrolled, like Apple’s interface for setting alarms and timers. I especially love it because it leaves open the possibility of interacting with the rest of the screen while an element is picked. Eg you could navigate a directory tree while finding the right place to put a file. Though I guess it’s similar to cut/paste in that respect. Nice. I actually did something similar 25 years ago, I called by think "pick-and-put". At that time I switched from MS-DOS environment to Windows 98. And as I was trying new UI features, I found drag-and-drop incredibly annoying. Especially if you do it between different windows, it requires a lot of movements, etc. I had an idea that going further into skeuomorphism can make things better, so I started experimenting with 3D UI, particularly, a file manager with 3D UI. And as an alternative to drag-and-drop I designed pick-and-put. It's actually very simple: right mouse button picks up an object and you get a symbol of that object next to the cursor. Then a click onto empty space puts it there. Or you can click a copy button which would copy it, etc. I think it could work really well if we got a convention that some mouse button always picks an object. But we don't. I don't think there's a way to make it works in the same way on desktop and mobile in a way which would be good. On desktop you have a mouse pointer, and you can easily represent point of insertion. For mobile you came up with this scroll trick, but I think many people would find it unintuitive and annoying - especially on desktop. I really don’t like this. It took me several attempts to figure out what was going on. And even after I had finally figured it out, it still felt more like a rendering glitch than good UX. If I struggled then I really can’t see this working for non-technical folk. Worse yet, because people wouldn’t expect this behaviour coupled with the fact that scrolling shouldn’t have any changes to the website state, you’ll likely see people constantly making accidental changes to the ordering of the list. On mobile this is a strong contender for the worst UX I've ever seen. The whole page moves, so you have to continously scroll back up after placing something. If when in pick mode you would only scroll the list, I would be able to organize it much faster. > On mobile this is a strong contender for the worst UX I've ever seen. Pretty hyperbolic. First of all, this is a human and their work you’re talking about. A little respect goes a long way. Secondly, if this is the worst UX you’ve ever seen on mobile, I have to assume you’ve only been using the internet for the past week or so. This experience worked great for me on mobile Safari with no instructions required. You can’t say that for a lot of mobile UX including, I might add, Safari itself. It's even worse on desktop. You have to scroll the entire screen (with mousewheel or arrow keys) to move the selection. I spent 30 seconds thinking it was bugged because the intuitive solution would be to click once, then simply click where you want to place it, but the "place" button only showed up on the one you already "picked". Fine idea, worst conceivable execution of UX I have ever seen. Perhaps a combination of the two? Maybe standard drag-and-drop works as usual, but if you drag the item to some deadzone (like the side of the screen?), it will stick and you're free to scroll to where you want to put it. Surely you're being hyperbolic. I've seen some atrocious UX before. Maybe what you mean is it's a good idea but the scrolling part should be list-based instead of page-based. No because what if the list is half cut off by the page but you want to go to the bottom? If it doesn’t scroll the page it’s even worse. If it does scroll the page it’s not great. It’s just bad design. Also not intuitive. I didn’t read the directions and it took me a couple seconds to get what was going on. Does not work with an indexed scrollwheel -- one click of the scroll wheel moves like 4 lines in your list, which seems to break the assumptions of your code. I get very strange behaviors, e.g. "pick" Five, scroll up and down, see swapping of Ten and Six during scroll. Then "place" results in Five being in the same place as before but Nine and Ten are swapped. Similar when using arrow keys. I have a regular scroll wheel and it moves two items each time. Totally unusable for me. (great idea, though) These feel like fixable things. Somewhat shockingly, apparently DOM does not give access to the raw scrollwheel data. The ones that are moving the wrong item to the wrong place are fixable, but there will always be a problem when scrolling is quantized if there is a possibility that any item in the list is shorter than the scroll quantum. It's interesting. I was expecting the bar to follow the cursor as you move it and clicking a second time would place it wherever it was. But, that's on desktop. The scrolling works a lot better on mobile. i was expecting when i click pick, that a "place" button would appear on each other item, or i could click on a row OR possibly highlighting the spots between rows either with a line, or "place" i think that's a much more intuitive & reliable ui, and would be an improvement on drag n drop. or a supplement to it I was expecting that the line item would move with my mouse movement, not with my scroll. That's a great idea actually. I'd have to find a way to highlight the possible landing spots. (i do like innovating on this btw) here's a basic CSS starting point Apple Newton had a way to drag/copy things around, a visual clipboard of sorts. They used a stilus, so it's similar. You drag an object to a side of the screen, where it turns into a visible but small handle and stucks. I think it could stay there any time and you could have several objects arranged this way. Then you can go anyplace, including a different application. Once you're in the right place, you could drag an object back and put it where you wanted to put it. But how are you going to replace the OG? https://mrcoles.com/dragondrop/ (Ironically doesn’t work on mobile) This reminds me of a UI pattern I saw in an old iOS comic reader (Comic Zeal) for organizing your comics. You had a horizontal rule that worked as a cursor. You could swipe things to the side (“pick”) to add them to the cursor. You then moved the cursor to the desired location and tapped it to dump the contents (“place”). My biggest problem with the OP implementation is the “place” button can be far from the “pick” button. Why not just leave it on the moving element - change the label from “pick” to “place” and call it a day. Given I need to read the instructions to understand how to use this, It's a no go for me. I clicked it and I thought there was a bug because I could only place on the element I clicked. The “place” aspect of the process needs some refinement. On iOS, it triggers the page bump (and necessitates and extra click) because it’s aligned at the bottom of the page. Having the “place” action hover near the selected object could be an alternative. I really enjoy this pattern. Nice work. cancel place should have some kind of a separator between them. I thought it is to cancel placing instead of two options to cancel or place. OK, so I get that you're trying an alternative on the metaphor that drag and drop uses. The metaphor is "pick up the item, move it, then drop it", but the implementation doesn't work well on mobile, so you made it modal. But for me scrolling feels like "pick up the item, move the rest of the world so the item above the target, then drop it". It feels very strange. As an refinement, I would keep the modality but add back in the dragging paradigm. Use a typical "move item" scrubber control, but have that control switch the item to a floating modality, and give it "send back" and "drop here" buttons. The user can drag the item, scroll, interact with the page, and the item stays with them to get where they want to go. Here is a crude mockup: https://excalidraw.com/#json=9DwYqkWRhdEgEEqyzY7X8,fCdPzIzTm... It’s good, I like it. I think that it might become easier to use if: - The whole item is clickable for the pick - Picked state is indicated clearly, possibly by hovering the item - You click on the item itself to place, or possibly anywhere on the screen Came to say that it badly needs better state communication. What I’d do is to add a drop shadow and increase scale by 1-3%, with a clean, snappy animation between placed and picked up. I might also add a “gripping hand” graphic with a cursor-like appearance to picked up items and show a “scroll to move” instruction next to the hand graphic if the user hasn’t done anything for a couple of seconds. This is very cool! I would still call this a 3-step approach, since you are performing 3 actions, but nonetheless, this UX interaction could be quite an improvement in some cases. That's neat. Not sure if I would deploy it, as it will be hard to explain/teach people how to use it (as I see in other comments already), but I do see the value in it. It solves the "drag and drop beyond what fits the screen" much better than you can with drag and drop, the awkward auto-scroll-on-nearing-the-edge-thing. I would say, if you need to reorder many items, it gets a bit disorienting, the whole list moves as it's anchored to the item you are moving. Maybe there is a way to combine drag and drop where this kicks in if you go beyond the bounds of the visible area. Also don't think this can work well with multiple axis/drop zones. I wonder if a stack metaphor would work for that. So that N items are no bigger than 2 items. Why "click, scroll and drop", rather than "click, point and drop"? The latter seems more general, works in 2D, and doesn't require two-finger mouse scrolling. I'm old enough to remember when using a mouse felt like being unchained. I also remember how quickly dragging began to feel like a time waste, even more so after spending more time on CLIs than GUIs. So though this seems limited to vertically arranged DOM things it's very cool for eliminating the least productive/most frustrating stage of drag-drop interactions Would love to see this work with keyboard only I could see this being really useful for editing lists that are longer than the page. The example that immediately comes to mind is reordering a playlist on YouTube Music, which currently requires dragging to near the screen edge and trying to convince the list to scroll while you still hold on to the item you're trying to move. Yessss this exactly! Moving songs up/down in large playlists would be fun with this concept. I wish that was a thing for music apps. When I had to implement a UI for reordering a list, I just had a “move” button on each item, and when you press it “move here” buttons would appear between every item (and at the top and bottom). These buttons are positioned absolutely, so there is no reflow from stretching the list. The location where you ‘place’ the item is where you click, not dependent on scroll position. Without even planning for use on mobile it ended up “just working” on mobile because you only need to tap buttons. The amount of time it took me to figure out how to use this I am embarrassed to say was too long. Yeah me too. It was only on third try that I realized I shouldn't move the cursor but just scroll :D As a ux designer, I like this, especially as it solves the problem of dragging mobile elements below the fold or off the visible screen view. One suggestion I'd love to try out- let the user select multiple elements at once, and reorder the selected elements in the hovering state using conventional drag and drop mechanics. This might add complexity or might be a much more convenient way to deal with lists! Or, dragging the element selected should allow a user to manually ‘place’ the item on screen. I wouldn’t use this on desktop, though! Mice typically allow you to scroll and drag pretty easily. This is fantastic. It didn’t work for me at first bc i dragged assuming it was dnd, but then would say that is “user error” 9/10 for originality. 2/10 for usefulness. Not bashing, that's how good ideas are found. But not this time IMO :) I think you could play with sticky footers, sticky headers, and some active styling indicators like opacity and background plus highlights to let the user know they are in scroll mode. Really fun idea, love this! Wish Apple Music UI for moving songs on playlists had that. Holding my dumb while dragging is suboptimal comparing to click and scroll. How move an item from the top to the bottom? Do you need to add 100% padding to the top and bottom of every list? Most lists can't be scrolled far enough to get the screen coordinates of the top to the bottom. It seems like it only works on pages that scroll, which is not good. I deleted the <header> and <footer> elements on the page, and was unable to anything but "cancel" after clicking "pick". Also did not work setting max-height on the <main> element and overflow-y:scroll, even though I could scroll the items did not scroll with it. It is an experiment and probably doesn't have every implementation detail covered yet. This actually caused a constant switching of attention on mobile. Each time an element is picked up I'll have to look at the bottom toolbar, then the floating element in the center, then back to the bottom to place it, so on and so forth. And the list in the demo is not that long yet. ------ Will this work on lists that sre short? It seems that it relies on overflow to move the element Neat concept, but why scroll the entire page? It just ends up being distracting and confusing. Once you hit "pick" the scroll action should affect just the list and nothing else. It’s been a long time since I’ve said “woah” out loud to something that wasn’t a science video. This is much better on mobile and I suspect for accessibility. Cool idea. Imo, Place should take Pick’s slot instead of being outside. There s probably something I didn’t think if that orevents this… Interesting concept but kind of unintuitive to figure out without reading about it first. Maybe you can tweak it? Interesting concept. Not sure if I like it more than drag and drop though, but I do love explorations like this. Reminds me of the old days when Flash devs would build some truly crazy stuff. Potential bug: The first time I tried it on my iPad, it didn’t place the item, but it did on subsequent uses. Very cool concept. Several people have made good suggestions on improving the UX. If I were implementing I’d probably try to support a stack of picked items so I could grab several and move them all at once. On mobile I wish there were a way to lock the browser window from scrolling. It was really disorienting with both the window and the list item moving. I repeatedly clicked pick and place and scratched my head for a minute. Wish there were a cue that I have to scroll. I instinctively tried to tap on the object again to place it, and I think that should be the default. This doesn’t appear to always work? Sometimes the placed item gets sent back to the original position even though it’s clearly being placed in a new spot (at least from what I can see visually). The UX idea is nice. Ideas for usability:
-Add a background behind the buttons when you have picked.
-When having picked, display above the buttons a helper text like "Now scroll to change position". CSS outline would be a good visual indicator here as it won’t modify the page layout. Came here to write the same. Give it some visual state of “pickedness“ (e.g. by displaying this state as elevated). But in any case, great stuff! you should perhaps mention that this is about dragging and dropping objects in lists. otherwise there is an additional level of jarring-ness due to not even knowing what problem you're trying to solve (and then bewildered by what it does as a result). Really nice, I found it highly intuitive on first use. Only thing I might suggest is making it more obvious what the "handle" button is that initiates the pick. Doesnt work, place just reverts on mobile safari. Even if it worked this adds steps. Oh, lovely. Let's play with this problem. Variations to consider: - Zoom out after drag start and back in when hovering over items. - Drag to a staging area/clipboard. https://github.com/jgthms/picknplace.js/ Linked in page is 404. Your link is 404 (is that what you meant?) Their page uses
https://jgthms.com/picknplace.js/picknplace.js For mobile, this seems like a good, maybe even better solution than the status Quo. Maybe not so much for desktop. The keyboard arrows to move works nice, but pressing enter to place appears to cancel it. I'm on firefox 145/mac os 15.6.1 if that matters. how does it work with more complex layout not just vertical list of items, like those drag-and-drop for visualization UI: https://github.com/Kanaries/graphic-walker you can see that there are different areas of draggable and droppable, on different directions. Viewing this on my phone and tapping the colored does nothing at all. Are they supposed to do something? Regardless of the technical and UX merit of this project. There are clearly a bunch of people who haven't used a new interface in perhapse years and are simply obtuse. It took me less than 5 seconds to start using this one handed while I was pissing at a urinal, I mean that quite literally. Honestly when I see things like this, I feel Ai can steal our coding but it can NEVER still our resoning and creativity. Thanks for sharing! Great, maybe highlight the item so we can distinguish the picked item from the others without scrolling. Interesting. Definitely see its potential for mobile pages. On web it feels unintuitive to scroll. It feels more natural to drag and drop. Guess Trello boards have conditioned us. But on web this control is way better. I completely got the point of it, however, I wanted to do something that was easy with this and not so easy with traditional drag and drop, which is move an object down several screenfuls. If it had 50 items rather than 10 I think it would be better for both those who easily see the advantage of this method and those who don't. Ditch the scroll. Pick: all previous "Pick" buttons become "Place". You choose one. Done. Simple, explicit, intuitive. Not trying to diminish the work at all because it works well but I hate this UX pattern. There is likely a reason this hasn't been done. If it wasn't for the pick -> scroll -> place instruction I would have no idea how to use it. a bit confusing, but lovely original idea, well made demo too thanks for sharing
