Bootstrap dropdown-toggle close on click

Question

I have a dropdown button with a list of things that are anchored to different parts of the page. This dropdown is only for mobile.

However the problem is, the dropdown would not close after I click on it. Is there anyway I can make it close on click? I've tried looking around but it wouldn't work on mine.

<div id="mobile-dropdown" class="nav2 w" data-spy="affix" data-offset-top="350">
                <div class="container">
                  <div class="pull-left" style="margin-top:3px; margin-right:3px;">Jump to </div>
                  <div class="pull-left">
                    <div class="btn-group mob-fl">
                         <button type="button" class="btn btn-default btn-sm dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
                            Categories
                         <span class="caret"></span>
                         </button>
                       <ul class="dropdown-menu" role="menu">
                          <li><a href="#1">One</a></li>
                          <li><a href="#2">Two</a></li>
                          <li><a href="#3">Three</a></li>
                          <li><a href="#4">Four</a></li>
                       </ul>
                    </div>
                  </div>
                </div>
              </div>

I also took a look at bootstrap's js itself and caught this line:

if ('ontouchstart' in document.documentElement && !$parent.closest('.navbar-nav').length) {
    // if mobile we use a backdrop because click events don't delegate
    $('<div class="dropdown-backdrop"/>').insertAfter($(this)).on('click', clearMenus)
  }

Is this be the reason why it won't close? Are there any workaround to make it work?

EDIT:

So with some help i got this script:

$('document').ready(function() {
      $("a.dropdown-toggle").click(function(ev) {
          $("a.dropdown-toggle").dropdown("toggle");
          return false;
      });
      $("ul.dropdown-menu a").click(function(ev) {
          $("a.dropdown-toggle").dropdown("toggle");
          return false;
      });
  });

My javascript is pretty weak, how do i actually edit this to make it work only in my "mobile-dropdown" id div.

Alright so far I've updated my script to this:

$('document').ready(function() {
  $("#subject_cat_mob .dropdown-toggle").click(function(ev) {
      $("#subject_cat_mob .dropdown-toggle").dropdown("toggle");
      return false;
  });
  $("#subject_cat_mob ul.dropdown-menu a").click(function(ev) {
      $("#subject_cat_mob .dropdown-toggle").dropdown("toggle");
      return false;
  });
});

It works like how I want it to be. But the dropdown won't open again after the first time.

This should make it work for your HTML:

$('document').ready(function() {
    $("#mobile-dropdown .dropdown-toggle").click(function() {
        $(this).dropdown("toggle");
        return false;
    });
});

Update

Here's a working example including your smooth scroll functionality:

$(function() {
    $('a[href*=#]:not([href=#])[href^="#"]:not([data-toggle])').click(function() {
        $(this).dropdown("toggle"); // this is the important part!

        if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
            var target = $(this.hash);
            target = target.length ? target : $('[name=' + this.hash.slice(1) +']');

            if (target.length) {
                $('html,body').animate({
                    scrollTop: target.offset().top-100
                }, 1000);
                return false;
            }
        }
    });
});

Notice the third line? That's all it needs: $(this).dropdown("toggle");.
