I want to make in our portal the "Please add more details" field a required field so that users have to add more information when raising requests. However because this is a default field I'm unable to make it an essential one
We are happy to let you know that this is now possible!
In the custom field layout for 'Ideas forms', you can now specify that any field on the form is required, including the standard Description (i.e. 'Please add more details') field.
