The idea is to bind (and trigger) conditional visibility of a Collection-List, to a custom element in the HTML structure.
This would allow to display a selection of Collection-List-Items with a click on a specific element.

Example:
I have a Collection-List with 5 Items.
When I click Button_A display only Item_1 and Item_2.
When I click Button_B display only Item_3 and Item_4.

I don't think this is possible right now, or am I missing something?
Cheers!
