I have a working vertical column drag and drop React app using react-beautiful-dnd, but would like to 'invert' it so that Draggable items fall to the bottom of the Droppable div instead of floating to the top. Is this possible?
If I'm understanding you correctly, you'd like to have a list where when the container is not full, the items within that list are aligned to the bottom of the container?
If so, then yes - I would utilize flexbox.
Here is a good resource for flex - https://css-tricks.com/snippets/css/a-guide-to-flexbox/
There are multiple different ways to implement this with flex. Pick your poison.

Based on the code sandbox:
I would add a wrapper div to the bay component with the same height as what you have now. On the child div, add a dynamic height field that is dependent on how many tables the bay contains.
Users won't be able to drop into the entire column but you could style it to show the user where they need to drop when the column is empty.
I ended up just creating another invisible strip with flexGrow = 1 to push everything to the bottom.

I created a draggable drag and drop table with draggable rows.
For the need of my project, i added multiple drop targets with multiple Droppable elements like in this example:
https://codesandbox.io/s/ql08j35j3q
It work pretty fine, but there is one problem, the scroll speed.
When i'm trying to drop an item in an element at the bottom of the page, it gets very slow.
This GIF will show the problem.
Do you have any clue for a solution ?
This may be a result of react-beautiful-dnd autoscroll, interfering with a css property called scroll-behavior. I just spent a day de-bugging this myself.
If you are using bootstrap, by default, bootstrap sets {scroll-behavior: smooth} to the entire html tag. To apply react-beautiful-dnd's fast auto-scroll, this css property should be {scroll-behavior: unset !important}
If you are not using bootstrap, or another library, check your css stylesheets, and see if {scroll-behavior: smooth} is set anywhere in any parent containers to your Droppables, and unset them.
A good way to debug this is by also opening Inspect Element in your browser, and looking at the styles applied to the html, body, or parent containers to your Droppables.
It appears that when scroll-behavior is defined in css or javascript( if you use window.scrollBy()), it may interfere with react-beautiful-dnd's fast auto-scroll feature, and make it slow.
Let me know if this works for you :) !
Here is my example in a gif - All the containers in the column are droppables
Referring to this question and answer by Shai Almog:
Rebuild list of containers without scrolling the list
I have a form with one container (TableLayout), which contains several rows with labels and buttons. Clicking a button changes the order of the rows and rebuilds the whole form (after myForm.removeAll() ). After myForm.revalidate() the form jumps to the top.
I am trying to implement this exact behaviour, to return to the same point (scroll position Y) after revalidating/changing the container contents.
I subclassed the Container-class to make setScrollY(int) visible. Using this with an arbitrary value does not scroll to the position, so it seems that the setScrollY method is not changing the scroll position of the content pane overall.
And myContainer.getScrollY() always returns "0". I only get the scroll position by calling getContentPane().getScrollY().
But it is obviously not possible to call the setScrollY()-method on the content pane - as it is not possible to subclass the content pane - to scroll back to the same position after revalidating the form.
Thanks for any advice!
Use border layout which disables the scrolling of the form/content pane.
Place your container (where you exposed setScroll) in the center and make sure to invoke setScrollableY(true) on that Container.
I'm not sure if this is the right place to ask because I dont have any code to show. I'm actually looking for ideas on possible ways to solve my problem.
I have an app that displays the grid on the screen when the media query has a min width of a tablet.
But when the view is in mobile mode I don't want to show the grid. Instead I have a drop down menu which has a grid option. When selected will be show in a paper-dialog (pop up)
The problem is I have to create two grids (vaadin-grid) and show the appropriate one based on the view. Is there a way to have only one grid? Can I put it in a paper-dialog but not pop-out when in tablet and desktop view?
Thanks in advance
If your grid element has every custom property then that is an element in the DOM, so you can move it into the dialog if thats needed using javascript:
let myGrid = this.$$('#myGrid');
let myDialogContent = this.$$('#myDialogContent');
Polymer.dom(myDialogContent).appendChild(myGrid);
Also if you think it a different way, then you can hide the grid outside of the screen and you can slide that in when it's needed like a drawer panel and you dont need to move the element at all in the DOM.
By the way for programming question stackoverflow has the https://softwareengineering.stackexchange.com/ site, but I think it is Ok to send it here.
I'm trying to create Custom Form configuration with scrollable TitleArea. The Form (black) has a BoxLayout.Y_AXIS Layout in BorderLayout.CENTER (blue). StatusBar (green) stays in BorderLayout.NORTH (green), when rest of the TitleArea (cyan) is in the first position in BoxLayout.
removeComponentFromForm function is unavailable for using in extended class. How can I remove components from Form to removing titleArea from BorderLayout.NORTH?
Why use the title area at all? Why not just add a component to the top of the box layout Y and style it as a Title that way you can scroll it out?
You can also use the new Toolbar API that includes many abilities to fade out the title as you scroll etc. See:

Please have a look on the following image.
How to display values along slider like bars with values ( Extremely unlikely, Neutral and Extremely likely ) as displaying in above image ?
I am fairly certain this is no built-in functionality for this. Make sure to always check out the Sencha Market in case someone made a custom component/extension/plugin though just in case.
My recommendation would be to create your own custom component, which should be simply a container with a vbox layout. First item should be your slider, second item probably another container with a hbox layout. Put your slider values as items under the hbox container with some custom CSS. Take it one step further if you want, and maybe in your constructor/initialize function add a listener to the slider and when it changes you can do something with the labels to indiciate the selected value.
