Custom CSS/only dropdown menu’s are something you can implement if you build the nav yourself.
Attach the proper CSS to Blocs app.
Put your markup for the menu inside one of Bloc’s “HTML Brics”.
It’s really that simple. You’ll lose the benefits of managing the links through the Blocs app, but it works, and it can be added to the dynamic section of the page the same as any Bloc/Bric making it available across your site if needed.
Hi, you can create simple navigation using text brics and links. You can even place an icon with visibility function activated to make it show/hide on a press. I think it will not use any js.
