      We have a (relatively) complicated setup where fields might become required or optional based on the value of other fields, so rather than keeping track of multiple rules, is it possible to set fields as required via JavaScript?

      Hi,
      Required fields are stored in this array:

      spjs.dffs.data.requiredFields

      and you can push in new fields like this

      // Push new required field into array
      spjs.dffs.data.requiredFields.push("YourFieldName");
      // Show star on all required fields
      spjs.dffs.starRequired();

      If you need to remove a field from the array, you can use this function:

      spjs.dffs.data.requiredFields = spjs.dffs.removeFromArr(spjs.dffs.data.requiredFields,"YourFieldName");

      Alex;

      1. It looks like spjs.dffs.flag_Mandatory(‘FieldInternalName’) will set the field to required AND show the red star on that field. Is that correct?
      2. Is there an internal dffs function that does the opposite? (that is, sets the field to optional and removes the red star on that field? Or a function just to remove the red start, if we use spjs.dffs.data.requiredFields = spjs.dffs.removeFromArr(spjs.dffs.data.requiredFields,”YourFieldName”) to make the field optional again?

      Sorry for the late reply – yes, you can use this snippet to do the opposite:

      spjs.dffs.clear_Mandatory(["Field1","Field2"]);
