Menu Settings - Enable Dropdown Menu on Hover (Pro Only)

By default, the dropdown menus open on hover. You can turn this off so that they will open on click. 

In order to change the setting, go to Appearance > Customize > Menus > Juliet Menu Settings and toggle the "Enable Dropdown Menu On Hover" on or off.

Please note - this will also turn off any menu levels deeper than parent and sub menu (so there will be no additional levels after the main dropdown menu).
