Hello,
I coming back with the same issue, that was marked as solved.
I put in megamenu configuration the width for a sub menu at 320px. for exemple.
I save, refresh the website, and the submenu text is on one line, prefect.
But as soon as i make changes in the megamenu configuration, other than the submenu width, something happens and delete the 320px width information, (i guess it is the problem), and then I have the submenu text information on two lines.
I've seen on a thread, that something is overwritting the information, somewhere...
Is there a solution for that, that prevent to enter each time the width submenu configuration ?
Thanks : )
