Help with a Pop Up window

I was going to use an element of this template - the pop up that appears when you click The How button in the Nav Panel.

I am able to edit the popup (its set to display none and 0% opacity)…but not able to see how to link it. There is no interactions or hover or press state. I’m not sure how it’s linked to the How button.

Thank you for your help!

Hi @K824 Kim, how you are well and this gets to you at a reasonable time.

What you are seeing is a legacy interaction, and you have to flip the switch in the interactions panel to see what is being done.

Here is a video I provided on the subject:

Good to know! Thank you!
