Web Accessibility Question: Keyboard Accessibility of Sub Menu's

[enlightworks]

Hello Weebly Community,

Does anyone know if it is possible to make sub menu's accessible via a keyboard so when a user tabs through the menu, they are able to do so with a keyboard on just the mouse? Where within the HTML/CSS could I add this functionality if possible?

Any HTML or CSS changes can by done by going to the Theme tab and clicking on "Edit HTML / CSS". Check the partials section on the left - I think that site navigation is included in there.
