Question

I am relatively new to JQuery, so please excuse this question if it seems trivial. I have a page, as outlined by the HTML below, with three tab elements, each of which may have an unspecified number of collapsible elements within. I am using a python dictionary called ‘groupings’ to pass data from the server, it’s structure is as follows:

groupings = {tab1: [[group, [(key, value), ...]], ...], ...}

I am using Twitter Bootstrap as a frontend framework and Jinja2 as a templating engine, with Python 2.7 on the backend. What I am unable to do with the following code is activate the collapsible elements. I am guessing that some JQuery is required that is different from that presented on the Bootstrap documentation. I have tried various permutations of the activating functions listed there, but because I am not yet very well versed in the use of JQuery, have been unsuccessful. Any help in doing so would be appreciated.

      <section id="tabs">
        <div class="page-header">
          <h1>Togglable tabs <small>bootstrap-tab.js</small></h1>
        </div>
        <div class="row">
          <div class="span9 columns">
            <ul id="myTab" class="nav nav-tabs">
              <li class="active"><a href="#tab1" data-toggle="tab">tab1 title</a></li> 
              <li><a href="#tab2" data-toggle="tab">tab2 title</a></li> 
              <li><a href="#tab3" data-toggle="tab">tab3 title</a></li> 
            </ul>
          <div id="myTabContent" class="tab-content">

Answer 1

The standard $('.collapse').collapse(); collapse activation would work in your case, but you are already using data-toggle="collapse". You shouldn’t use both.

As seen in this demo (jsfiddle), it works.

There is one thing that might cause an unexpected behavior : the accordions IDs are not unique. Any ID’ed element in a loop should be made unique :

<div class="accordion" id="accordion_{{category}}">
  <!-- ... -->
    <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion_{{category}}" href="#{{group[0]}}">...</a>
  <!-- ... -->
</div>
