Use radio buttons to select
Demo of Illustrated







Note: as this is a demo, you can't really upload files. However, you can browse for images on your system and test the Uploader widget.


By setting the option radio in the Uploader widget the aspect ratio is selectable through radio buttons as opposed to a dropdown list.

The other options of the Uploader widget are exactly the same as in this demo.
