How to create an overlay detail panel for a collection item when you click on it?

Hi community!

Here’s the deal: I have a list of card in my website whose content is fed by a Collection List (it’s the “prestation”). When the user click on one of the card, which is an item of the Collection, I want my website to display an overlay panel with more details on this item.

To do so, I created a panel template which is also fed by the same Collection List. The problem is that I don’t know how to ensure that when you click on a specific card, it display the corresponding panel…

I precise that I can’t put the card and the panel in the same Collection Component because I need to display my panel above everything, even my topbar.

Is there any way to do it? Custom code? Thanks in advance for the help!
