Custom Property Pane using Fluent UI Panel in SPFx

This article provide steps to implement the Custom Property Pane using Fluent UI Panel in the SharePoint Framework (SPFx) web part, generally Fluent UI Panels are modal UI overlays that provide contextual app information. They often request some kind of creation or management action from the user. Panels are paired with the Overlay component, also known as a Light Dismiss. The Overlay blocks interactions with the app view until dismissed either through clicking or tapping on the Overlay or by selecting a close or completion action within the Panel.

Create a new web part project

Open power shell and run following comment to create a new web part by running the Yeoman SharePoint Generator

yo @microsoft/sharepoint

When prompted:

Enter the webpart name as your solution name, and then select Enter.
Select Create a subfolder with solution name for where to place the files.
Select Y to allow the solution to be deployed to all sites immediately.
Select N on the question if solution contains unique permissions.
Select WebPart as the client-side component type to be created.

The next set of prompts ask for specific information about your web part:

Enter your web part name, and then select Enter.
Enter your web part description, and then select Enter.
Select React framework as the framework you would like to use, and then select Enter.

Start Visual Studio Code (or your favorite code editor) within the context of the newly created project folder.

cd .\web part name\
code .

Install the library and required dependencies

npm install @pnp/sp --save

Configure the custom properties

Create a new source code file under the src\webparts\<web part name>\components\ folder of the solution. Call the new file I<web part name>State.ts and use it to create a TypeScript Interface

import { IDropdownOption } from 'office-ui-fabric-react';
export interface ISpfxFluentuiPanelState {
  projects: IDropdownOption[];
  showpanel: boolean;
  projectname?: string;

Update the <web part name>.tsx file. First, add some import statements to import the types you defined earlier. Notice the import for I<web part name>Props and I<web part name>State. There are also some imports for the PnP components used to render the UI of the PnP React component and pnp sp imports.

import * as React from 'react';
import styles from './SpfxFluentuiPanel.module.scss';
import { ISpfxFluentuiPanelProps } from './ISpfxFluentuiPanelProps';
import { ISpfxFluentuiPanelState } from './ISpfxFluentuiPanelState';
import { autobind } from 'office-ui-fabric-react/lib/Utilities';
import { DefaultButton, PrimaryButton } from 'office-ui-fabric-react/lib/Button';
import { Panel, IDropdownOption, Dropdown, IStackTokens, Stack, IIconProps, TextField, } from 'office-ui-fabric-react';
import { sp } from "@pnp/sp";
import "@pnp/sp/webs";
import "@pnp/sp/lists";
import "@pnp/sp/items";
const stackTokens: IStackTokens = { childrenGap: 20 };
const addIcon: IIconProps = { iconName: 'Add' };

Replace this render function with the following code.

  public render(): React.ReactElement<ISpfxFluentuiPanelProps> {
    let buttonStyles = { root: { marginRight: 8 } };
    const onRenderFooterContent = () => (
        <PrimaryButton onClick={this._saveclick} styles={buttonStyles}>
        <DefaultButton onClick={this._cancelclick}>Cancel</DefaultButton>

    return (
      <div className={styles.spfxFluentuiPanel}>
        <Stack tokens={stackTokens} verticalAlign="end">
          <Stack horizontal tokens={stackTokens} verticalAlign="end">
            <Dropdown className={styles.Dropdown}
              placeholder="Select a Project"
            <DefaultButton text="Project" iconProps={addIcon} onClick={() => this.setState({ showpanel: true, projectname: '' })} />
        {this.state.showpanel &&
            headerText={"New Project Name"}
            <TextField placeholder={'Enter a new project name'} onChanged={(strproject) => this.setState({ projectname: strproject })}></TextField>


Update the React component type declaration and add a constructor, as shown in the following example.

export default class SpfxFluentuiPanel extends React.Component<ISpfxFluentuiPanelProps, ISpfxFluentuiPanelState> {
  constructor(props: ISpfxFluentuiPanelProps, state: ISpfxFluentuiPanelState) {
      spfxContext: this.props.context
    this.state = { showpanel: false, projects: [] };

Add below event functions and function to get list items from SharePoint to inside the react component

  private async _getProjects() {
    const allItems: any[] = await sp.web.lists.getByTitle("Projects").items.getAll();
    const options: IDropdownOption[] = [];
    allItems.forEach(function (v, i) {
      options.push({ key: v.ID, text: v.Title });
    this.setState({ projects: options });
  private async _saveclick() {
    if (this.state.projectname != '') {
      const iar = await sp.web.lists.getByTitle("Projects").items.add({
        Title: this.state.projectname,
      const projectsarr = this.state.projects;
      projectsarr.push({ key:, text: this.state.projectname })
      this.setState({ showpanel: false, projects: projectsarr });
    else {
      //here you can add code for show error message if project name is blank

  private _cancelclick() {
    this.setState({ showpanel: false });

Deploy the solution

You’re now ready to build, bundle, package, and deploy the solution.

Run the gulp commands to verify that the solution builds correctly.

gulp build

Use the following command to bundle and package the solution.

gulp bundle --ship
gulp package-solution --ship

Browse to the app catalog of your target tenant and upload the solution package. You can find the solution package under the sharepoint/solution folder of your solution. It is the .sppkg file. After you upload the solution package in the app catalog. you can find and the web part anywhere across the tenant.

Sharing is caring!

If you have any questions, feel free to let me know in the comments section.
Happy coding!!!

  1. Hi

    I have a requirement like asking for number of people to be part of the team and based on the number, text fields should get added dynamically to add their names in the webpart properties itself. I have to take the names from the web[part properties again and display in the webpart.

    How can I achieve this.

    Kind Regards,
