Hi @okraits,
I hope you're doing well.

I recently opened a PR — fix/[bug:ui] Select2 autofilter look is inconsistent with other filters (#541) — which closes issue #533. I’ve addressed the styling inconsistencies between Select2 autofilters and the regular admin filters and ensured tests and functionality remain unaffected.

Whenever you have time, could you please take a look and let me know if any changes are needed? Your feedback would be really helpful as I’m still getting familiar with the codebase.

Thank you!

This patch does not solve the issue. I am closing for now, feel free to reopen if you come up with an actual solution.

Hi @nemesifier,
thank you for taking the time to review the PR and for the feedback.

I understand that the current patch doesn’t fully resolve the underlying issue. I’ll revisit the problem, dig deeper into the root cause of the Select2 autofilter inconsistency, and work on a more accurate solution. Once I have a proper fix, I’ll reopen the issue with an updated approach.
