Thanks for reporting this. It seems we've got a bug here. Would you like to contribute to the project by investigating it?
@michaldudak @supidupicoder2 I would like to pick this up?
I investigated this a bit. It doesn't seem like it's the Select, but rather the Menu at fault. It's related to Menu.autoFocus
specifically on the selectedMenu
variant. I'm happy to submit a fix, but I want to verify the intended functionality first.
How it currently works is that it will focus either the first selected menu item, or the first item in the list if none are selected. As a user selects or deselects items, this focus element is re-evaluated and the focus changes, causing scroll. If a user deselects all items, it will then put focus back on the first menu item, causing it to scroll back to the top.
To fix this, I can think of a couple solutions:
The first one feels more proper to me personally, but it's also a larger change in how the component functions.
I found a second issue I can also fix where the select will auto-select the last item, rather than the first as the docs suggest.

Steps to reproduce ๐น
Link to live example: This happens on the official MUI Website (as of 10. July 2023): https://mui.com/material-ui/react-select/ (or alternatively, stackblitz: https://stackblitz.com/edit/react-gtavad?file=demo.tsx)

Current behavior ๐ฏ
The scrolling position of the popup will jump to the top of the Select popup.
If more than one item was selected and one item gets deselected, the scroll will not jump to the very top, but will focus one of the other selected items instead.
Expected behavior ๐ค
The scrolling position of the popup should stay where it is.
Context ๐ฆ
I want to be able to deselect something in a Select Component with the multiple prop, without the scrolling position of the popup jumping around.
There was a very similar issue back in 2021: https://github.com/mui/material-ui/issues/19245
Some other issue: This behaviour can be circumvented as described here: https://stackoverflow.com/questions/72955537/material-ui-select-jumps-to-the-top-of-the-page
But this will break other things: -) Keyboard not working properly anymore -) When opening the selection and there are already things selected, the popup should already focus on those things, not start at the very top, but this will be broken with the workaround.
