title: Bootstrap 2.3.2 Collapse two divs (only one active at a time)
body: <p>I have two divs that I want to add collapsible functionality with Bootstrap 2.3.2. Both divs are working, but I just want one div can be displayed at a time.</p>
  
  <p>I´m not using accordions. </p>
  
  <p>I created a plunker. But as you can see both divs can be opened at the same time.</p>

  <p>Code:</p>
  
  <pre><code>    &lt;a href="#paypal" data-toggle="collapse"&gt;Link_1&lt;/a&gt;
    &lt;div id="paypal" class="row-fluid collapse out"&gt;
          &lt;div class="span12"&gt;
              Testing collapsible text 1
          &lt;/div&gt;                              
      &lt;/div&gt;
  
      &lt;a href="#creditCard" data-toggle="collapse"&gt;Link_2&lt;/a&gt;
    &lt;div id="creditCard" class="row-fluid collapse out"&gt;
          &lt;div class="span12"&gt;
              Testing collapsible text 2
          &lt;/div&gt;                              
      &lt;/div&gt;
