title: Upload multiple files with a single input element
body: <p>I have a simple input for "file".</p>
  
  <p>I was wondering how I go about making it so you can select multiple files using one input.</p>
  
  <pre><code>&lt;input name="sliderfile" id="sliderfile" type="file" /&gt;
  </code></pre>
  
  <p>Basically, multiple select in one browse window.</p>
  
  <p>Any help would be appreciated,</p>
  
  <p>Thanks!</p>
