Allows to have an exposed filter only show options that belong to result set.
Install this module using the official Backdrop CMS instructions at
Add a field to the view that you want to use as a distinct field.
Configure the field output in as you wish.
If you do not want this field to be shown in the result set,
just mark it as "Hide From Display".
Add a filter of type "selective" to your view, and in the filter settings
select the field you configured. If the field is not showing, that means
that the filter and field you are trying to match are not compatible.
You can get 3 types of errors with this module:
(a) You did not properly match a filter and a field.
(b) You properly matched filter and field, but base field is not the same.
You get the same error text as in (a).
(c) You choose a field whose distinct value has more than the limit (100 by default)
different possible values, obviously this field is not the kind of field you
would use for a selective filter.
