This feature is used to hide the ENTIRE location native HighLevel menu.
It is useful when you are rebuilding / replacing the Native HighLevel Location Menu (from scratch) with your own Custom Location Menu with the GHL Customizer because it can be time consuming to hide every individual menu item with the GHL Customizer.
NOTE: When HighLevel releases a new menu item, it will not automatically appear in the menu because the ENTIRE menu is hidden and ONLY the items you add in with the GHL Customizer will appear.
It leaves the Settings area and Agency area unchanged.
This option is NOT recommended if you are using the HighLevel Custom Menu Links.
