To prevent my Superfish Main Menu from stacking as screen size decreases - and thus obscuring the content below it, I set sf-Smallscreen to change the Superfish Main Menu to an accordion when the screen size scales down to 990px. This accommodates tablets in portrait orientation, for example.
Problem: When you scroll down on a tablet, the accordion "Button" reverts to the Desktop rendering of the Main Menu, "stacking up" because it's too wide for the narrow screen.
Scroll back up and the Desktop Main Menu is replaced by the accordion.
Question: How can make the accordion button persist when scrolling down on a tablet-sized screen?
