I'm trying to make the mobile responsive menu on a bootstrap site disappear completely by clicking on its links. The site is one page and the links work through Anchors. The site has been modified in a theme theme by another person. I think the class - nav bar toogle collapse - needs to be modified from the bootstrap. I tried searching for the errors in the JS files but I did not find them. Follow the link in the theme to responsibly test the code and prints as an example. Thank you to anyone who solves the problem, I'm waiting for you. Theme builder: link
