Make a menu unroll AND open at the same time


I have a problem with my theme on this website :

As you can see, on the left sidebar there is a navigation menu called “NAVIGATION”. And as you can see, most of these menus have a small “+” (plus) symbol on the right.

When we click on this “+” symbol, the sub-menu open (drops down below the main menu element), which is good…

…BUT when we click on one main menu element (for exemple “L’essentiel en bref”:wink:, then the page opens, but the sub-menu doesn’t drop down as when we clicked on the “+”.

In my opinion it’s not ergonomic : when a user clicks on a main menu element, sure the page should open, BUT the menu itself should also “open” and display the sub-menu elements, just like when we just click on the “+” symbol.

Is there a way to do that ? I’m sure there is as it’s a small thing, but I have no idea how to do that.

Thanks a lot for the continuous great help guys ! :slight_smile:
