Multiple file uploads are supported with WebViewGold. Make sure to add the multiple attribute to your HTML upload form:
<input type="file" id="files" name="files" multiple>
On iOS, you are required to tap three dots in a circle icon in the title navigation after tapping “Browse”. Then, choose “Select” from the dropped-down menu, select more than one file, then touch “Open” in the title menu.
On Android, you need to press long (!) on the first file, and then you can select more than one file.
