setDataSupport(support: Partial<PanelPluginDataSupport>): this;

Parameters

Returns:

this

Example

import { ShapePanel } from './ShapePanel';
interface ShapePanelOptions {}
export const plugin = new PanelPlugin<ShapePanelOptions>(ShapePanel)
    .useFieldConfig({})
    ...
    ...
    .setDataSupport({
      annotations: true,
      alertStates: true,
    });

setDefaults method

// when plugin should only display specific standard options
// note, that options will be displayed in the order they are provided

 .useFieldConfig({
   standardOptions: [FieldConfigProperty.Min, FieldConfigProperty.Max]
  });
// when standard option's default value needs to be provided
export const plugin = new PanelPlugin<ShapePanelOptions>(ShapePanel)
 .useFieldConfig({
   standardOptions: [FieldConfigProperty.Min, FieldConfigProperty.Max],
   standardOptionsDefaults: {
     [FieldConfigProperty.Min]: 20,
     [FieldConfigProperty.Max]: 100
   }
 });
// when custom field config options needs to be provided
export const plugin = new PanelPlugin<ShapePanelOptions>(ShapePanel)
 .useFieldConfig({
   useCustomConfig: builder => {
     builder
      .addNumberInput({
        id: 'shapeBorderWidth',
        name: 'Border width',
