Customize Item
Documentation
The Form component can create form items automatically for each field of the formData object. If you’d prefer to configure form items manually, pass the required array of configuration objects to the items property. You can specify the name of the bound data field, editor type, editor configuration, validation properties (etc.) for each form item.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
