File Upload - Add to existing Input <p>I have the following file input box that allows for multiple upload: </p> <pre><code>&lt;input name="filesToUpload[]" id="filesToUpload" type="file" multiple="" /&gt; </code></pre> <p>My users pick their files and they appear in a list. But say after picking their files a user wishes to add more files without overwriting the existing files chosen. Is it possible to add on to the list of existing files or would I need a new file input element?</p>
