On this website my client would like to have the menu title

Hi!

On this website my client would like to have the menu title (in this case 'Vrijwilligerswerk') in the sidebar to be a clickable link. How can I achieve this?

I tried:

Vrijwilligerswerk

but it only makes the word Vrijwilligerswerk (menu title) a lot smaller and it doesn't become clickable...

Any idea on what to do to make the menu title in the sidebar clickable?

thanks!
