Hi Jesse,
Sorry this is not a response for a resolution to you pop-up menu but I just wanted to welcome you to Webflow. Your title, “From Adobe Muse to Webflow” caught my attention because I have recently started with Webflow as I transition from Adboe Muse. I am liking it so far but it is taking me some time getting used to building with sections, inline blocks, etc.
Wishing You Sucess.
