Opening sub-level menu by clicking on text

Hello,

In the burger menu, how could i make the first level item clickable to open the sub-level menu ? For the moment only the arrow pointing to the bottom is clickable to open the sub-level menu.

On the exemple in the attached file, i’d like that a click on the “Manufacture” text opens the sub-menu “La Manufacture – Notre équipe – Nos cavaliers”.

Thanks for your help.
