How to implement a secondary menu?

It sounds like you’re looking for a sub-menu for the current menu item from another menu – if that makes sense itself 😉

One that I’ve personally used with great success is Advanced Menu Widget. Tons of options and does exactly what you want. Thanks!

Features include:

  • Custom hierarchy – “Only related sub-items” or “Only strictly related
    sub-items”.
  • Starting depth and maximum level to display + flat
    display.
  • Display all menu items starting with the selected one.
  • Display only direct path to current element or only children of
    selected item (option to include the parent item).
  • Custom class for a
    widget block.
  • And almost all the parameters for the wp_nav_menu
    function.
