I have made a user form. There is a part for checkboxes in a generic field. This is the code:

[cred_generic_field type='checkboxes' field='welke-voorkeursdagen']
        {
            "required":1,
            "default":[],
            "persist":1,
            "options":[
                {"value":"1","label":"Maandagochtend"},
                {"value":"2","label":"Maandag middag"},
                {"value":"3","label":"Dinsdagochtend"},
                {"value":"4","label":"Dinsdagmiddag"},
                {"value":"5","label":"Woensdagochtend"},
                {"value":"6","label":"Woensdagmiddag"},
                {"value":"7","label":"Donderdagochtend"},
                {"value":"8","label":"Donderdagmiddag"},
                {"value":"9","label":"Vrijdagochtend"},
                {"value":"10","label":"Vrijdagmiddag"}
            ]
        }
        [/cred_generic_field]

It is not showing me the This is required message. Is there something wrong with this code?

Hello. Thank you for contacting the Toolset support.

To validate the checkboxes field, you will have to use the server side validation hook "cred_form_validate":
- https://toolset.com/documentation/programmer-reference/cred-api/#cred_form_validate

Following example may help you, you can adjust the code for field names etc.. as required.
