Hello Warren,
Yes, it does work! Although this functionality is not natively supported, it is possible to apply a work-around solution.
Please have a look at this fiddle: https://jsfiddle.net/mozhbqfe/1/
The function inside the event, triggered on ‘pointerdown’, replaces the default text field with a drop down list and then passes the selected value back to the text field.
Using a similar method, it is possible to use any other jqWidgets Component inside CardView.
If you have any other questions, please do not hesitate to contact us again.
Best Regards,
