You have the close icon prominent there so now you need to give it function
setup a page custom state and call it mobilemenuvisible? of type yes/no … set it to default “no”
set the fg to be not visible
set two fg conditions. one to be visible when mobilemenuvisible is “yes” and another one to not be visible when it is “no”
set two workflows when clicking the close icon (the “X”) with a condition in each. the first one with a condition when mobilemenuvisible is “yes” and the second one on the second workflow to when mobilemenuvisible is “no”
for the first workflow’s action find the action that says “set custom state” and set the custom state of the page… guess which one? … the only one we established which is mobilemenuvisible to be “no”
set the second workflow’s action to set it to “yes”
