Bootstrap nav menu in BC(3rd level dropdowns)

Question

Hi everyone,
I am making a module V2 bootstrap nav menu in BC but i cant get the 3rd level  ITEM_1_1  and Items Item2_1_ and item  ItEM2_1_1 to open,
Here's the code of the file children.html for  this.
<li class="dropdown"{tag_menuitemidname_withid} {tag_menuitemcssclass_withclass}>
<a class="dropdown-toggle" data-toggle="dropdown"  href="{tag_menuitemurl}">{tag_menuitemlabel}
</a>
<ul class="dropdown-menu">
{tag_menugroup}
</ul>
</li>
the code for the group.html:
<ul class=" nav">{tag_menuchilditem}</ul>
and the code for the container.html:
<div class="navbar navbar-inverse navbar-fixed-top">
  <div class="navbar-inner">
    <button type="button" class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button>
    <div class="nav-collapse collapse">
      <div id="1529273">{tag_menugroup}</div>
    </div>
  </div>
</div>
How can this be done in BC?
