Briefly stated, I am trying to build a single page format web app. Which means I will need to manually hide the elements (lets say elements of first page) while I am working with others (elements of second page after login).
The problem happens when I try to work with elements in “responsive mode” (not in UI builder mode) where NOT all the elements are available on the left panel.
In the UI Builder mode I can see the rest of the elements but in the responsive mode they do not. Is this a known bug or I am doing something wrong?
