Question/Feature Request: Additional user search/filtering on related_views.

[steve-embling]

Environment

Flask-Appbuilder version: Flask-AppBuilder==3.4.5

Describe the expected results

I expected the ability for users to filter on additional fields on top of the parent ID in a related list view, similar to the usual list modelview. Is this possible in any way? Main reason is for select-all and and multiple item actions it would be useful when you have lots of child items.

Right now it seems to need leaving the related view and navigating to the child item's own list view and then manually configuring the same parent ID filter along with the extra filters - which is a bit unfriendly when everything else already accessible from the related_view.

Is this behaviour supported in any way or on the roadmap?

Describe the actual results

Any filtering queries via GET do not filter the related_view items, and the search accordion isn't present for related_views.

Swear i searched open and closed issues, pull requests, stack overflow and google for well over an hour looking for anyone raising this before.

Thanks, I'll give this a try over the next couple days - is there any indication outside that thread and PR as to why the needed changes to the framework were not accepted?

Edit: Just tested now, and sure enough - seems to work great from a few quick checks!

Really appreciated, thank you.
