Well I went to Navigation and Site Submenu. Do you mean I add new Item or Add new Menu because in Site Submenu the choice is new Item. By going to Menu only, I was able to create with Add New Menu'' ''Donation'' but it didn't come under About in the menu. See picture. What I want to do is do have Donation under About in the menu. Sorry for my ignorance but I'm new to this.
Hello caribman2020 !
If you have already the new menu and set within + you already set this menu as a submenu for the "About us" to then you need to edit the "About us" point via the following way:
2) add the "bx_menu_popup('[the submenu name]', this);" code to the Onclick field's value;
The submenu name can be known in the Studio->Developer->Navigation area.
