I have a problem with the sub menu on mobile, which is already expanded when I click on the hamburger menu (as seen in the attachment). The submenu has a blue background color. My website is www.via-wm.com.
I would like to have it collapsed. I tried using the plugin mega menu but I didn’t succeed.
Customization does not mens only to change files, it also means to create a new style and add it to the existing elements, so, it’s not so explained, if you done this before then it should be easy this time too
