I have two menus in my header. And currently, in the mobile version, the simple menu only list my MENU 2. I wonder how can I add up the two menus or at least change it to display MENU 1.
Presumably it’s in a file that’s included in your global footer (this is fairly standard in HubSpot templates). I’d navigate to the design manager and edit the global footer for the page you’re referring to for the relevant Javascript file.
It might be easiest to combine those two menus into a single menu. That would allow the existing menu Javascript to function with all of your menu options. Otherwise, you’ll need to customize the existing mobile menu Javascript to target multiple menus.
