Add to filter ability to select multiply values from custom field with 'Type = Selection'
NetBox version
v4.2.2
Feature type
New functionality
Proposed functionality
First, I will show the problem on screenshot. We have custom field 'Client' with type = Selection. The selection stores several thousands of choises. We use this custom field in rack object.
When we try to use rack filter and select several values from custom field 'Client', we can't do it. Netbox allows to choose only one choice.
My proposal is to implement ability to choose several values in filter for custom fields with type = selection.
Use case
This feature improve user experience working with netbox. Also it saves time to get information from netbox based on some criteria.

I had a quick look at the CustomField.to_form_field() helper. As it stands, the TYPE_SELECT custom field always maps to a single-value choice field & widget, even when it’s used to build filter forms. That’s why the rack filter UI only allows picking one value from a selection-type custom field today.
To address this, I’d like to extend to_form_field() with a for_filter_form flag, similar to the existing for_csv_import argument. When for_filter_form=True and type == TYPE_SELECT, we could return a multiple-choice field (e.g. using APISelectMultiple), while keeping the existing behavior unchanged for create/edit/bulk-edit forms.
If this approach sounds acceptable, I’d be happy to pick this up and open a PR.
