If you’d like to show the menu to everybody, regardless of user role (in other words, to act like a normal menu item), simply select the “By Role” option and do not check anything off the list. This will ensure that anybody visiting your site can see the link. This is also the default option when new items are added to your menus, so if you don’t want to restrict access, you don’t have to do a single thing.
Example based on my need:
I was hiding Custom Field Template on the Post page, so i went to the bottom of the post options, then added the name in the left text area (Custom Field Template in my case, for your reference so it can be anything...) and the selector for the element in the right (# for ID and . for class - so i entered #cftdiv)
Name for option in left -> selector in the right
Click "Update Options"
Go back down and find your newly created option and select the boxes as needed
