class="click-modal"should do the trick, maybe?
Mmm nice idea (I wonder if I didn’t tested 6 month ago) but there is a mask above the modal content (it’s a big modal) and over all this look weird. I think this is because the customSearch start to run the loading wheel/mask as the modal open but it stays stuck with it.
This is how the link look "https://local:8890/blabla/item4378-itemtitle"
I imagine I could add "another" list plugin to do exactly as I want, but this is already a customSearch using a template with 4 different trackers (cascading) and it start to be heavy (slow).
Is there a way to tweak the relation field type output ? (where this is ?)
