Flippable Card Variable?

Hello,

I wish to know the state of my flippable card (flipped or not) but I can't set actions for the flippable card widget.

My goal is to do the following :

• I display a list of things to the users

• They can select whatever they want

• When they select it, the card is flipped

• I want to know wich cards are flipped

I could use a checkbox but I liked the animation and style of flippable cards

Thanks for your help
