Hello,

Yes, when you add child menu items to a parent, it automatically becomes and anchor for mobile devices. Otherwise on mobile devices when trying to open the sub-menu, it would take you directly to the Services section or page.

If you would like it to behave differently I would suggest installing and using this menu plugin https://wordpress.org/plugins/megamenu/

You will just need to modify the header.php file of our theme to insert the php code for the megamenu plugin.
