What this code does is to check if there's a child element under the dropdown with current state ('.w--current' class added by webflow), and apply the same class to the parent dropdown element.
We start by adding this short code to the Project's custom code section, so this will work globally on any page in the project.. We can also add this manually to every page we have a sub level dropdown menu.
var hasActiveLink = $(this).find('.w--current').length > 0;
When your bath soap bar gets too small to use, don't throw it away! open the next bar, and when you finish showering, stick the small old bar to the back of the new bar. Onces they both dry, they will become one.
