Hi Charlie,
There seems to be a possible bug with the CS Forms datepicker element. I have tried using it on several websites, all with the same result.
My basic setup is as in the screenshot - note I am using two separate fields for date and time:
On the front end, the fields are greyed out, but when clicked, the calendar does not appear. The only way I can get the calendar to display is if it is set Inline. Click to Open does not seem to do anything.
Any ideas what could be going on?
Thanks,
Christopher
