How can I disable an option based on date condition?

We have a form that allows booking for a selection of training courses. Booking for a course close 7 days before the course date. Is there a way to disable an option in an option field based on a date condition.

Unfortunately, it's not possible to disable an option from a field by a condition. You will have to manually remove the option or do the following workaround:

1. Separate the options into multiple fields.

2. Add DateTime field in the form with default date.

3. Add a conditional logic in the form to hide the fields based on a date.

Hi Welvin,

I understand that there is not out-of-the-box solution. Would you have any tips how I could go about finding a Javascript based solution. Sort of along the lines: Use jQuery to find all the relevant radio button elements, extract the date from the value attribute (first 10 characters) of each element. If date < current date + 7 days set the element to disabled.

I did play around a bit but could get anything going. Probably the because the form is drawn somehow delayed and the elements are not there when my Javascript runs. Just some pointers would be good as I can sort out the finer details myself.

Thanks

Sure, I'll look at it and let you know of the Javascript workaround. But this would need you to get the source codes and embed it as it is after adding the script(s). 

Getting the source and embedding it is fine, I expected that - thanks
