Is it possible to add a custom validator to a dynamic content type field?
Suppose to have a short text field named "Agency Code" which value must be validated on an external database table. How can I do that?
Kaloyan answered me that this functionality is not available out of the box.
Kaloyan suggested to implement a custom solution, that is to subscribe to one of the exposed events for module builder and trigger our custom validation. More detailed information about the available events can be found from the link below:
