DFF-How to control Date field

Summary:

Hello team,

I will try to explain my requirement-

Process-I have created a task which is of configurable form in the checklist template. In the task, there are various custom fields and End Date is one of the fields. So, Performer will complete the task and also fill End Date field.

Once, submitted the form, then we want to revoke the request asked in the Configurable form according to the End Date. It means, when End Date comes, the request has to be revoked.

Requirement- We want to control End Date field in such a way that End Date -should show dates equal and greater than Start Date.
