Menu is limited to to one submenu. Here is a tutorials how you can get one more sub-level for your menu. It is written for Sparkling WordPress theme but it will work the same way for Unite WordPress theme as well with some small tweaks.
Hi,
I have set up the plugin with the correct settings. I am able to select the drop down menu however the functions do not work properly now. When I set up an accordion list it does not show properly, it appears as a heading which appears to be linked to nothing in particular and the text below the heading. When the settings are as default, the accordion appears correctly as a drop down of information when the heading is clicked, but then I cannot select the drop down menu from the primary website menu.
I am using the Travelify theme, what do you suggest?
