Scenario: Hari wants to create a dynamic form where certain fields become required based on user selection. For example, if a user selects 'Other' for a category field, a text field for specifying the category should become required. How should he implement this?

Override clean() method to check field values and conditionally raise ValidationError if dependent fields are empty

Use JavaScript to dynamically show/hide fields based on user selection

Create multiple forms and switch between them based on selection

Use Django signals to modify form fields after initialization
