Under my menu tab “Resources,” I would like to add a link to an outside website but have an exit warning message popup when they click it. I am not sure how to connect the message to the menu button.
Hi vlmanha,
Thank you for contacting us.
In your case what you can do is target a message on click of link.
So that whenever user clicks on link message will show and then it will redirect to website.
For details step by step docs on “How to Trigger a message on click” refer this link.
