jQuery Mobile - Open Collapsible-set with URL parameter

Question

Using jQuery Mobile, can a panel in the collapsible-set (accordion?) be open by default? For example, have the second panel, "Title 2", open on page load. I have not found any information on this and would like to do this based on a URL parameter.

Here's the html I have currently:

<div data-role="collapsible-set">
  <div data-role="collapsible" data-theme="c" data-content-theme="b">
    <h3>Title 1</h3>
    <div>Text 1 inside here</div>
  </div>
  <div data-role="collapsible" data-theme="c" data-content-theme="b">
    <h3>Title 2</h3>
    <div>Text 2 is here</div>
  </div> 
  <div data-role="collapsible" data-theme="c" data-content-theme="b">
    <h3>Title 3</h3>
    <div>Text 3 inside this div</div>
  </div>   
</div>

Here is a fiddle as well:

          <h3>Title 1</h3>
          <div>Text 1 inside here</div>
     </div>
     <div data-role="collapsible" data-theme="c" data-content-theme="b">
          <h3>Title 2</h3>
          <div>Text 2 is here</div>
     </div> 
     <div data-role="collapsible" data-theme="c" data-content-theme="b">
          <h3>Title 3</h3>
          <div>Text 3 inside this div</div>
     </div>   
</div>
