Create Field
Creates a new field in a Formdesk form. Use this action to add fields like text inputs, email fields, textareas, checkboxes, date pickers, etc. to an existing form. You must have the form ID from FORMDESK_GET_FORM_LIST or FORMDESK_GET_FORM_DETAILS before creating fields. The field definition should specify at minimum the field name, type, and label. Additional properties like 'required', 'placeholder', 'description', and 'default' can be included.
