How to use this control in your solutions

  1. Check that you installed the @pnp/spfx-property-controls dependency. Check out The getting started page for more information about installing the dependency.
  2. Import the following modules to your component:
import { CalloutTriggers } from '@pnp/spfx-property-controls/lib/PropertyFieldHeader';
import { PropertyFieldDropdownWithCallout } from '@pnp/spfx-property-controls/lib/PropertyFieldDropdownWithCallout';
  1. Create a new property for your web part, for example:
export interface IPropertyControlsTestWebPartProps {
  dropdownInfoHeaderKey: string;
  1. Add the custom property control to the groupFields of the web part property pane configuration:
PropertyFieldDropdownWithCallout('dropdownInfoHeaderKey', {
  calloutTrigger: CalloutTriggers.Hover,
  key: 'dropdownInfoHeaderFieldId',
  label: 'Select the version',
  options: [{
    key: 'v1.0.0',
    text: 'v1.0.0'
  }, {
    key: 'v1.0.1',
    text: 'v1.0.1'
  }, {
    key: 'v1.0.2',
    text: 'v1.0.2'
  }, {
    key: 'v2.0.0',
    text: 'v2.0.0'
  calloutContent: dropdownInfoHeaderCallountContent
  1. Implement the calloutContent function as follows:
private getDropdownInfoHeaderCalloutContent(): JSX.Element {
  const selectedKey: string =;

  if (selectedKey) {
    return React.createElement('div', {}, `you have selected ${selectedKey}`);
  } else {
    return React.createElement('div', {}, `you haven't selected any version`);


The PropertyFieldDropDownWithCallout control uses the same implementation as the default PropertyPaneDropdown and has the following additional properties:

Property Type Required Description
