Menu Settings - Show Dropdown Menu On Click (Pro only)
Version 2.0+. By default, the theme shows the drop down menus on the main navigation when the user hovers over the items.
However, you can choose to disable this option by going to Appearance > Customize > Menus > Kale Menu Settings and disable the Enable Dropdown Menu On Hover option.
Please note, if you turn this off, the menu will only show 2 levels: the main level and the dropdown level. No further levels (for example main>sub>sub) will be shown.
