Field autocomplete widget add scrollbar

Forgot to mention - we use the gin admin theme version 3.0.0-rc9. Also added a patch that adds a scrollbar.

Hi @Vadym.Tseiko, @saschaeggi,
Fix the issue and created MR. please review it once.

Scroller is added but not able to view all the tags in that autocomplete field. Unable to scroll till the end.

Not able to reproduce the issue.
I can only see 10 default suggestions for the autocomplete field and this is the default behaviour of any drupal theme.
Attaching the screenshot for the same.
Please provide some more details for reproducing the issue.

Unable to reproduce

step followed :
create a entity reference field with unlimited values.

but after 10 result no other results are visible.

Hi @vadym.tseiko,
I have checked #2 patch and its working fine at my end. I am also attached the screen-shot for references.

+RTBC Done

If you need more than 10 result than kindly follow below steps.

- Navigate to Manage form display for your content type.
- Click on the gear icon next to your entity reference field to edit its settings.
- Check if there are any options for controlling the autocomplete behavior or limiting the number of results.
- Set here maximum number here and save.
- Edit your content and type the text and see there autocomplete result will more than 10.

Hey 👋

I left some comments in the code. Also note that the source files are missing, so moving this back to needs work

I wonder if we better fix this in Core instead of here so other themes can benefit of this, too.
