exit burger menu by clicking outside

Hi. I'm trying to make my forced desktop burger menu exit when clicking outside of the menu, as well as on the 'X'. Can anyone help?

Thank you

Interesting question! What code did you use to force the mobile menu on desktop?

Was a purchase? or a free plugin? 

Please remove this post. That is my hamburger menu on desktop plugin. It is not free it is a paid plugin and is my copyrighted work.

For any customization support please email me directly. If you did not purchase it from me where did you get it so I can contact that person?

This is concerning. 😞

@Chris.SE Didn't recognize that as one of yours, hence my earlier question, I was asking to recommend getting direct support if it was purchased.

Thanks for removing the post Tom. I got your email and will follow up with you there!
