To change the default settings, declare an item configuration object. Use the dataField property to bind an item to a field in the formData object. Use the editorType property to specify an item's data editor or configure the editor in the editorOptions object. You can also specify any other properties described in the SimpleItem section.
To customize item labels, use the label.template property. The demo uses this property to add icons to the labels. Refer to the Additional Notes item's implementation for instructions on how to add an icon with a tooltip to the label.
This demo shows how to specify editorOptions, editorType, validationRules, and colSpan properties for simple items in a Form component.
