Ever had to combine 2 menus using the default WordPress Menu editor. Manually it can take a while to copy over all the details from 1 menu to another.
This does all the leg work for you by copying all the elements of the menu into the menu you are currently editing, keeping its sub-menus.
How to use
- Go to Appearance > Menus and open the menu you want to add to.
- Find the Merge Menus box on the left. If it is not there, open Screen Options at the top of the screen and tick Merge Menus.
- Choose the menu to copy from and press Merge Menu. Its items are added to the bottom of your menu, with their sub-menus.
- Press Save Menu. Nothing is kept until the menu is saved.
The menu you copy from is never changed. Merge Menus works with classic menus (Appearance > Menus), not the Navigation block.
