template: helix ultimate anchor menu (mobile) after clicking on the link or closing - the menu is hidden, the page returns

I have such a script

/ smoth scroll to ancor # / jQuery(function($){ $('a[href^="#"]').click(function(){ var target = $(this).attr('href'); $('html, body').animate({scrollTop: $(target).offset().top-0}, 900, 'swing'); return false; }); });
