How to have a non-link menu item
By default, every menu item will contain a link – an anchor with href attribute to a specific URL – which will redirect when clicked.
Sometimes, you don’t want an item to link to anything specific, or to redirect at all when clicking. In this case, you can enable the Disable Link setting in the menu item settings. The anchor will be replaced with a <span> which is styled the same but won’t link to another page.
Full Item Toggle – how to turn the entire parent item into a toggle
For items that have submenus (child items), if the Disable Link setting is checked, the entire item will act as a toggle for the submenu, rather than just the submenu arrow icon.
