title: Cannot fire "CheckAll" Method - jQuery UI MultiSelect Widget
body: <p>I'm trying to have all of my options selected in my <a href="http://www.erichynds.com/jquery/jquery-ui-multiselect-widget/" rel="nofollow noreferrer">Multiselect</a> widget on startup.</p>
  <p>In the documentation, it says:</p>
  <blockquote>
  <p>After an instance has been initialized, interact with it by calling any of these methods:</p>
  <p>// example:<br />
  $(&quot;#multiselect&quot;).multiselect(&quot;method_name&quot;);</p>
  <p>checkAll ------   Check all checkboxes.</p>
  </blockquote>
  <p>So I did this:</p>
  <pre><code>$(&quot;#music&quot;).multiselect(&quot;checkAll&quot;);
  </code></pre>
  <p>And this is the error I got:</p>
  <blockquote>
  <p>Error: cannot call methods on multiselect prior to initialization;<br />
  attempted to call method 'checkAll' [Break On This Error]</p>
  <p>throw new Error( msg );</p>
  </blockquote>
  <p>Any ideas? Thanks!</p>
