Showing active menu on a drop down side menu on Bootstrap (AdminLTE)

Question

I want to highlight the active page on the side bar menu. I am using Bootstrap (AdminLTE).

I have tried a number of javascript ways to no avail. Kindly anyone help out. Below is the side bar menu.

<ul class="sidebar-menu" >
  <li class=""><a href="/dashboard"><i class="fa fa-dashboard"></i> <span>Dashboard</span></a> </li>
  <br>
  <li class="treeview">
    <a href=""> <i class="fa fa-cogs"></i> <span> Account Configuarion</span> <i class="fa fa-angle-left pull-right"></i> </a>
    <ul class="treeview-menu">
      <li class="treeview">
        <a href=""> <i class="fa fa-mobile fa-lg"></i> <span>M-PESA C2B</span> <i class="fa fa-angle-left pull-right"></i> </a>
        <ul class="treeview-menu">
          <li class=""><a href="/c2b"><i class="fa fa-arrow-circle-right"></i>C2B Settings</a></li>
          <li class=""><a href="/online-checkout"><i class="fa fa-arrow-circle-right"></i> Online CheckOut</a></li>
          <li class=""><a href="/stk-push"><i class="fa fa-arrow-circle-right"></i> STK Push</a></li>
        </ul>
      </li>
      <li class="treeview">
        <a href=""> <i class="fa fa-mobile fa-lg"></i> <span>M-PESA B2C</span> <i class="fa fa-angle-left pull-right"></i> </a>
        <ul class="treeview-menu">
          <li><a href="b2c-documentation"><i class="fa fa-arrow-circle-right"></i>  B2C Settings</a></li>
        </ul>
      </li>
      <li class="treeview">
        <a href=""> <i class="fa fa-send"></i> <span>SMS</span> <i class="fa fa-angle-left pull-right"></i> </a>
        <ul class="treeview-menu">
          <li class=""><a href="/sms-setting"><i class="fa fa-arrow-circle-right"></i>SMS Settings</a></li>
          <li class=""><a href="/subscription"><i class="fa fa-arrow-circle-right"></i>Subscription SMS Settings</a></li>
        </ul>
      </li>
    </ul>
  </li>

  <li class="treeview ">
    <a href="#"> <i class="fa fa-cogs"></i> <span>Account Info</span> <i class="fa fa-angle-left pull-right"></i> </a>
    <ul class="treeview-menu">
      <li class=""><a href="buy-units"><i class="fa fa-arrow-circle-right"></i> Buy Units</a></li>
      <li class=""><a href="/account-details"><i class="fa fa-arrow-circle-right"></i>Account Details</a></li>
      <li class=""><a href="/users"><i class="fa fa-arrow-circle-right"></i>Account Users</a></li>
    </ul>
  </li>
</ul>

I tried with this javascript code but ends up opening all the dropdowns. All the same, it does highlight the current item. But I would want the other items remain closed and only active remains open.

<script>
    $(document).ready(function() {
        var url = window.location; 
        var element = $('ul.sidebar-menu a').filter(function() {
        return this.href == url || url.href.indexOf(this.href) == 0; }).parent().addClass('active');
        if (element.is('li')) { 
             element.addClass('active').parent().parent('li').addClass('active')
         }
    });
    </script>

Answer 1

/** Try this ** > for sidebar and treeview menu in adminLTE, it will add active when clicked and remove any previous active class /** to add active class and remove previously clicked menu */

var url = window.location;
// for sidebar menu but not for treeview submenu
$('ul.sidebar-menu a').filter(function() {
    return this.href == url;
}).parent().siblings().removeClass('active').end().addClass('active');
// for treeview which is like a submenu
$('ul.treeview-menu a').filter(function() {
    return this.href == url;
}).parentsUntil(".sidebar-menu > .treeview-menu").siblings().removeClass('active menu-open').end().addClass('active menu-open');
