@Pearl1594 , I could not fine domain on the add compute offering modal, but then

Thanks Daan. I've addressed it at other places.
Regarding domain dropdown menu - that is visible when public field is unchecked.

looks great @Pearl1594 and I think we can merge as is, but I also found some select fields in the add backup offering that do not move with the parent when scrolling.
(sorry for my diligence)
I think a search for a-select on teh whole ui project makes sense. I wonder why this behavior is not default in ant3d.

[shwstppr]

@Pearl1594 I think this will be needed across UI if we want consistent behaviour. Maybe we need to create a new custom select component which enforces this behaviour. For starters, if we want to change it in just the offering forms, that is fine too.

[DaanHoogland]

I agree @shwstppr , merging this is a good start but enforcing behaviour with a systemwide component makes sense.

[Pearl1594]

I agree as well. I think that's a better way to move ahead. Thanks.
