Hello,
I'm using the J51-Substance template on a website and I can't get the mobile menu working. The "hamburger" doesn't show. Instead the hole menu is shown on the site (see attachment)
I have made a module for the menu in the hornav-mobile position.
I'm using Joomla version 3.8.3
URL is: http://www.stichtingveen-depeel.nl/
Thanks for the support,
Frits
