Multiple Selection Widget by JotForm drop down is hidden

When I embed my form with this widget, the drop down is hidden, it doesn't do it's normal 'auto grow' anyone else having this issue?
When I preview the form it works, but it does not work when java embedded.

Here's form I built for troubleshooting this, note that the issue is only when embedding the form.

Hi,

The reason of it being cut off is because the container height is too low.

re-embed using the Iframe method then set the Iframe height to around 900px, you can also set the height to auto (height:auto;)to allow for auto-grow.
