title: Sitecore field for selecting multiple files from media library with the ability to upload files
body: <p>I'm looking for something that allow content editors to select multiple files from the media library, which will be listed in a rendering. They also need to be able upload files and to search. It has to work in the Page Editor (named Experience Editor in version 8).</p>
  
  <p>What I have have considered so far:</p>
  
  <ul>
  <li>A bunch of File fields - but I don't know how many files the editor need to select at most, and having something like 20 similar fields seems bad.</li>
  <li>Using a field that supports multiple items like a Treelist with the datasource set to the Media Library allows the user to select files in an acceptable way but not uploading. I tested adding one File field just for the upload function, but was not really satisfied. </li>
  </ul>

  <p>Notes: </p>
  
  <ul>
  <li>Currently using Sitecore 7.5 but moving to 8 in a few days, so a solution working in Sitecore 8 is preferred.</li>
  <li>I have asked the Sitecore support too and will update here if I get useful answers.</li>
  </ul>
