Hoe kan je voorwaardelijk verplichte velden instellen in een pdf?

@Dave Creamer of IDEAS You can run a Javascript.

Create a radio button with two choices: Private and Firm (or similar).

Create a Javascript action for each.

This _should_ work but I’m not an expert programmer…

First, set all fields except radio button to Read Only.

For Private:

this.getField("PrivateField01").readonly = false; // Unlocks field
this.getField("PrivateField01").required = true;   // Optional: Makes required

Repeat for each Private field, then do a similar thing for the Firm fields.

Another option:

var fieldsToLock = ["Students Name", "District ID", "Grade", "Date"]; // Replace with your field names

for (var i in fieldsToLock) {
    var field = this.getField(fieldsToLock[i]);
    if (field) {
        field.readonly = true;
    }
}
