Hello,

I'm currently playing around with PCF in combination with Office UI Fabric React.

I use the Dropdown control as seen here but inside the PCF test harness the styling doesn't look like it. (see screenshot).

Does anyone have a clue what I'm missing?

My TSX

import * as React from 'react';
import { Dropdown, IDropdownOption } from 'office-ui-fabric-react/lib/Dropdown';

export interface IEntityMetadataDropdownProps {
 entityLogicalName?: string;
 entityMetadataType?: ComponentFramework.PropertyTypes.EnumProperty<"All" | "Custom" | "System">;
 entityLogicalNameChanged: (newValue: string) => void;
}


const options: IDropdownOption[] = [
 { key: 'apple', text: 'Apple' },
 { key: 'banana', text: 'Banana' },
 { key: 'grape', text: 'Grape' },
 { key: 'broccoli', text: 'Broccoli' },
 { key: 'carrot', text: 'Carrot' },
 { key: 'lettuce', text: 'Lettuce' }
];

export class EntityMetadataDropdown extends React.Component<IEntityMetadataDropdownProps> {
 constructor(props: IEntityMetadataDropdownProps) {
 super(props);
 }
 
 public render(): JSX.Element {
 return (
 <Dropdown placeholder="Select an entity" options={options} selectedKey={this.props.entityLogicalName} onChange={this._onChange} />
 );
 }

 private _onChange = (event: React.FormEvent<HTMLDivElement>, option?: IDropdownOption): void => {
 if(option){
 const selectedKey: string = option.key as string
 if (this.props.entityLogicalNameChanged) {
 this.props.entityLogicalNameChanged(selectedKey);
 }
 }
 else{
 this.props.entityLogicalNameChanged("");
 } 
 };
}

Index.ts (It's based upon the react example)

import { IInputs, IOutputs } from "./generated/ManifestTypes";
import * as React from "react";
import * as ReactDOM from "react-dom";
import { EntityMetadataDropdown, IEntityMetadataDropdownProps } from "./EntityMetadataSelector"


export class EntityMetadataSelector implements ComponentFramework.StandardControl<IInputs, IOutputs> {

	private notifyOutputChanged: () => void;
 	// reference to the container div
	private theContainer: HTMLDivElement;
	 
 private props: IEntityMetadataDropdownProps = {
		entityLogicalNameChanged: this.entityLogicalNameChanged.bind(this)
	};

	/**
	 * Empty constructor.
	 */
	constructor()
	{

	}

	/**

	 public init(context: ComponentFramework.Context<IInputs>, notifyOutputChanged: () => void, state: ComponentFramework.Dictionary, container:HTMLDivElement)
	 {
		// Add control initialization code
		this.notifyOutputChanged = notifyOutputChanged;
		this.props.entityLogicalName = context.parameters.EntityLogicalName.raw || undefined;
		this.props.entityMetadataType = context.parameters.EntityMetadataType;
		this.theContainer = container;
	 }

	}

	private entityLogicalNameChanged(newValue: string) {
		// only update if the number of faces has truly changed
		if (this.props.entityLogicalName !== newValue) {
		 this.props.entityLogicalName = newValue;
		 this.notifyOutputChanged();
		}
	 }

	/**

	 * @returns an object based on nomenclature defined in manifest, expecting object[s] for property marked as “bound” or “output”
	 */
	public getOutputs(): IOutputs
	{
		return {
			EntityLogicalName: this.props.entityLogicalName
		 };
	}

	/** 
	 * Called when the control is to be removed from the DOM tree. Controls should use this call for cleanup.
	 * i.e. cancelling any pending remote calls, removing listeners, etc.
	 */
	public destroy(): void
	{
		// Add code to cleanup control if necessary
		ReactDOM.unmountComponentAtNode(this.theContainer);
	}
