Trigger nested tab pane on Bootstrap 3

Trigger nested tab pane on Bootstrap 3

I'm developing a site using latest bootstrap release, and I need some help
to figure out how to solve this:
I've nested two tab panes, to be able to manage a lot of information in
little space (It´s a very long law and I need to show its articles
clearly)
The first tabs divides the main sections, the nested shows in little
pieces the articles.
It works fine in the main container.
But I´ll need a navigation tree in the sidebar, and I can´t trigger the
nested pane tab if the parent one isn´t already enabled.
I think it could be posible to add some jquery to trigger the parent tab
when clicking a direct link to a nested one, but I don´t get it... :(
This is the code (my apoligies, I see it too long):
<!-- Sidebar -->
<div class="bs-sidebar" role="complementary">
<ul id="test">
<li><a href="#test_1" data-toggle="tab">Title I</a>
<ul>
<li><a href="#test_11" data-toggle="tab">Sub_Title I</a></li>
<li><a href="#test_12" data-toggle="tab">Sub_Title II</a></li>
</ul>
</li>
<li><a href="#test_2" data-toggle="tab">Title II</a></li>
<!-- ... -->
</ul>
</div>
<!-- main container -->
<div role="main">
<h2>Some Title</h2>
<div class="bs-example bs-example-tabs">
<div class="panel panel-default">
<div class="collapse navbar-collapse navbar-ex1-collapse">
<ul id="tabs" class="nav nav-tabs">
<li><a href="#test_1" data-toggle="tab">Title I</a></li>
<li><a href="#test_2" data-toggle="tab">Title II</a></li>
<!-- ... -->
</ul>
</div>
<div class="panel-body parent">
<div id="tabs_parent" class="tab-content">
<div id="test_0" class="tab-pane active fade in">
<p>Instructions</p>
</div>
<div id="test_1" class="tab-pane fade">
<ul>
<li><a href="#test_11" data-toggle="tab">Sub_Title I</a></li>
<li><a href="#test_12" data-toggle="tab">Sub_Title II</a></li>
</ul>
<div id="tabs_children" class="tab-content">
<div id="test_11" class="tab-pane fade">
<p>Sub-I Lorem ipsum dolor sit amet...</p>
</div>
<div id="test_12" class="tab-pane fade">
<p>SubII - Morbi lectus nibh...</p>
</div>
</div>
</div>
<div id="test_2" class="tab-pane fade">
<p>Morbi lectus nibh...</p>
</div>
<!-- ... -->
Thanks in advance :)
