when i visit the website on a mobile (Androind + Chrome), when i click on a voice of the menu or submenu there is a background colour light blue.

You must create a separate menu for the mobile display, and assign it to the menu burger.

And another question regarding the menu:

Edit your header template, open hamburger menu element options, and you will find options for that in the Style tab.

I am using the mega menu for my project and I was able to customize everything for desktop but I cannot change the colors in the mobile menu.

I'd like to remove the side bar menu (hamburger menu), I've looked and can't find it neither in widgets nor in the BeBuilder.

Sorry for the misunderstanding. I thought you referred to assigning templates to menu items, not setting the template as a menu item.

You must create a sidebar menu template, add a logo and menu to it, and adjust its display for your needs.

Indeed it was a 'template menu item' that was causing this issue. I did mention it back on Feb. 23. Wish that someone caught it and saved me 5 days of frustration. Also mentioned it in our emails back

Thanks, but this is not about building a menu; it's about customizing a hamburger menu pop-u with logo etc . See my initial post.

To me it looks like this comes from the social links in the menu of the website. As I am not having any social links in my menu / website I wanna know, how I can get rid of this.

In the Templates tab, you must open Screen Options and disable all SEO-related info.

When you open Theme options and save them, everything should go back to normal.

You must open theme options, disable this option, save changes, and enable it again.

We found the root cause. Your menu items are templates (?) which are visible only for logged users as they are just templates, not actual pages.

In Appearance -> Menus, you must open Screen Options, and check Link Target option.

Hi, I need to link one navigation point as an external link, however I cannot make it open on a new tab...

The two mega menu links also don't show up in the hamburger menu, nor in the footer when logged out.
