title: Multiple data-target in Bootstrap?
body: <p>In bootstrap you can toggle a <code>.collapse</code> element using button as I have done in my code.
  I am new to Bootstrap and understand that we are using <code>data-toggle</code> to select the property and <code>data-target</code> to select the element. But is there any way/syntax/options for multiple element and properties to be selected sth like <code>data-target="#demo + #demo1 + #demo2"</code>?</p>
  
  <pre><code>    &lt;button type="button" class="btn btn-primary dropdown-toggle btn-sm" 
  data-toggle="collapse" data-target="#demo"&gt;
      &lt;div id="demo" class="collapse in"&gt;Demo&lt;/div&gt;
      &lt;div id="demo1" class="collapse in"&gt;Demo1&lt;/div&gt;
      &lt;div id="demo2" class="collapse in"&gt;Demo2&lt;/div&gt;
  </code></pre>
