HELP! Menu won't disappear on mobile

I’m brand new to Webflow, and purchased a template and customized it but now the menu isn’t working properly on mobile. It won’t go away even when you click it so now nobody can view the site on a mobile device. I’ll need a very detailed step by step to help me out!
