SharePoint 2013 Hosting – HostForLIFE :: How To Use PnP React Accordion Control In SPFx?

Accordion menus and widgets are widely used on websites to manage a large amount of content and navigation lists. In this article, we will see step by step implementation of the accordion with SharePoint list.

Scenario

In this example, we will create a list called “Accordion” and in the list, we will create a Description field (it will be multiple lines of text -Rich text) and will use Title and Description field to expand and collapse.

We will use PnPJs to get list items and then will render them in the accordion form.

At the end, our output will be like this,

Let’s see the step-by-step implementation.

Implementation

Create a list with Title and Description fields as mentioned above.
Open a command prompt
Move to the path where you want to create a project
Create a project directory using:

md directory-name

1	md directory-name

Move to the above-created directory using:

cd directory-name

1	cd directory-name

Now execute the below command to create an SPFx solution:

yo @microsoft/sharepoint

1	yo @microsoft/sharepoint

It will ask some questions, as shown below,

After a successful installation, we can open a project in any source code tool. Here, I am using the VS code, so I will execute the command:

code .

code .

Now we will install pnpjs and pnp-spfx-controls-react as shown below:

npm install @pnp/sp --save    
npm install @pnp/spfx-controls-react --save --save-exact

1 2	npm install @pnp/sp --save npm install @pnp/spfx-controls-react --save --save-exact

Now go to the src > webparts > webpart > components > I{webpartname}Props.ts file,

import { WebPartContext } from "@microsoft/sp-webpart-base";  
  
export interface IPnpReactAccordionProps {  
  description: string;  
  listName: string;  
  context: WebPartContext;  
}

import { WebPartContext } from "@microsoft/sp-webpart-base";

export interface IPnpReactAccordionProps {

description: string;

listName: string;

context: WebPartContext;

}

Create a file I{webpartname}State.ts inside src > webparts > webpart > components and create state interface as below,

interface IListItem {  
    Id?: string;  
    Title: string;  
    Description: string  
}  
  
export interface IPnpReactAccordionState {  
    listItems: IListItem[];  
    errorMessage: string;  
}

interface IListItem {

Id?: string;

Title: string;

Description: string

}

export interface IPnpReactAccordionState {

listItems: IListItem[];

errorMessage: string;

}

Create a Service folder inside src and then in this folder create a file called SPService.ts. And in this file, we will create a service to get list items as below,

Here list name will come from the webpart property pane.

import { WebPartContext } from "@microsoft/sp-webpart-base";  
import { sp } from '@pnp/sp/presets/all';  
  
export class SPService {  
    constructor(private context: WebPartContext) {  
        sp.setup({  
            spfxContext: this.context  
        });  
    }  
  
    public async getListItems(listName: string) {  
        try {  
            let listItems: any[] = await sp.web.lists.getByTitle(listName)  
                .items  
                .select("Id,Title,Description")  
                .get();  
            return listItems;  
        } catch (err) {  
            Promise.reject(err);  
        }  
    }  
}

import { WebPartContext } from "@microsoft/sp-webpart-base";

import { sp } from '@pnp/sp/presets/all';

export class SPService {

constructor(private context: WebPartContext) {

sp.setup({

spfxContext: this.context

});

}

public async getListItems(listName: string) {

try {

let listItems: any[] = await sp.web.lists.getByTitle(listName)

.items

.select("Id,Title,Description")

.get();

return listItems;

} catch (err) {

Promise.reject(err);

}

Now move to the {webpartname}Webpart.ts. And create a list name property in property pane configuration and pass context and list name property as below,

import * as React from 'react';  
import * as ReactDom from 'react-dom';  
import { Version } from '@microsoft/sp-core-library';  
import {  
  IPropertyPaneConfiguration,  
  PropertyPaneTextField  
} from '@microsoft/sp-property-pane';  
import { BaseClientSideWebPart } from '@microsoft/sp-webpart-base';  
  
import * as strings from 'PnpReactAccordionWebPartStrings';  
import PnpReactAccordion from './components/PnpReactAccordion';  
import { IPnpReactAccordionProps } from './components/IPnpReactAccordionProps';  
  
export interface IPnpReactAccordionWebPartProps {  
  description: string;  
  listName: string;  
}  
  
export default class PnpReactAccordionWebPart extends BaseClientSideWebPart<IPnpReactAccordionWebPartProps> {  
  
  public render(): void {  
    const element: React.ReactElement<IPnpReactAccordionProps> = React.createElement(  
      PnpReactAccordion,  
      {  
        description: this.properties.description,  
        listName: this.properties.listName,  
        context: this.context  
      }  
    );  
  
    ReactDom.render(element, this.domElement);  
  }  
  
  protected onDispose(): void {  
    ReactDom.unmountComponentAtNode(this.domElement);  
  }  
  
  protected get dataVersion(): Version {  
    return Version.parse('1.0');  
  }  
  
  protected getPropertyPaneConfiguration(): IPropertyPaneConfiguration {  
    return {  
      pages: [  
        {  
          header: {  
            description: strings.PropertyPaneDescription  
          },  
          groups: [  
            {  
              groupName: strings.BasicGroupName,  
              groupFields: [  
                PropertyPaneTextField('description', {  
                  label: strings.DescriptionFieldLabel  
                }),  
                PropertyPaneTextField('listName', {  
                  label: strings.ListNameFieldLabel  
                })  
              ]  
            }  
          ]  
        }  
      ]  
    };  
  }  
}

import * as React from 'react';

import * as ReactDom from 'react-dom';

import { Version } from '@microsoft/sp-core-library';

import {

IPropertyPaneConfiguration,

PropertyPaneTextField

} from '@microsoft/sp-property-pane';

import { BaseClientSideWebPart } from '@microsoft/sp-webpart-base';

import * as strings from 'PnpReactAccordionWebPartStrings';

import PnpReactAccordion from './components/PnpReactAccordion';

import { IPnpReactAccordionProps } from './components/IPnpReactAccordionProps';

export interface IPnpReactAccordionWebPartProps {

description: string;

listName: string;

}

export default class PnpReactAccordionWebPart extends BaseClientSideWebPart<IPnpReactAccordionWebPartProps> {

public render(): void {

const element: React.ReactElement<IPnpReactAccordionProps> = React.createElement(

PnpReactAccordion,

{

description: this.properties.description,

listName: this.properties.listName,

context: this.context

}

);

ReactDom.render(element, this.domElement);

}

protected onDispose(): void {

ReactDom.unmountComponentAtNode(this.domElement);

}

protected get dataVersion(): Version {

return Version.parse('1.0');

}

protected getPropertyPaneConfiguration(): IPropertyPaneConfiguration {

return {

pages: [

{

header: {

description: strings.PropertyPaneDescription

groups: [

{

groupName: strings.BasicGroupName,

groupFields: [

PropertyPaneTextField('description', {

label: strings.DescriptionFieldLabel

}),

PropertyPaneTextField('listName', {

label: strings.ListNameFieldLabel

})

]

}

]

}

]

};

}

Move to the {webpartname}.tsx file and then bind the service using current context and the call service for get list items and set values in the state and render it in accordion control as below,

import * as React from 'react';  
import styles from './PnpReactAccordion.module.scss';  
import { IPnpReactAccordionProps } from './IPnpReactAccordionProps';  
import { IPnpReactAccordionState } from './IPnpReactAccordionState';  
import { escape } from '@microsoft/sp-lodash-subset';  
import { SPService } from '../../../Service/SPService';  
import { Accordion } from "@pnp/spfx-controls-react/lib/Accordion";  
  
export default class PnpReactAccordion extends React.Component<IPnpReactAccordionProps, IPnpReactAccordionState> {  
  
  private _services: SPService = null;  
  constructor(props: IPnpReactAccordionProps) {  
    super(props);  
    this.state = {  
      listItems: [],  
      errorMessage: ''  
    }  
    /** Bind service using current context */  
    this._services = new SPService(this.props.context);  
  }  
  
  public componentDidMount() {  
    this.getListItems();  
  }  
  
  /** Get items of selected list and set values in state */  
  private async getListItems() {  
    if (this.props.listName) {  
      let items = await this._services.getListItems(this.props.listName);  
      this.setState({ listItems: items });  
    }  
    else {  
      this.setState({ errorMessage: 'Please enter the list name in property pane configuration.' });  
    }  
  }  
  
  public render(): React.ReactElement<IPnpReactAccordionProps> {  
    return (  
      <div className={styles.pnpReactAccordion}>  
        {  
          //Map list items and render in accordion  
          (this.state.listItems && this.state.listItems.length) ? this.state.listItems.map((item, index) => (  
            <Accordion title={item.Title} defaultCollapsed={true} className={"itemCell"} key={index}>  
              <div className={"itemContent"}>  
                <div className={"itemResponse"} dangerouslySetInnerHTML={{ __html: item.Description }}></div>  
              </div>  
            </Accordion>  
          )) : <p>{this.state.errorMessage}</p>  
        }  
      </div>  
    );  
  }  
}

import * as React from 'react';

import styles from './PnpReactAccordion.module.scss';

import { IPnpReactAccordionProps } from './IPnpReactAccordionProps';

import { IPnpReactAccordionState } from './IPnpReactAccordionState';

import { escape } from '@microsoft/sp-lodash-subset';

import { SPService } from '../../../Service/SPService';

import { Accordion } from "@pnp/spfx-controls-react/lib/Accordion";

export default class PnpReactAccordion extends React.Component<IPnpReactAccordionProps, IPnpReactAccordionState> {

private _services: SPService = null;

constructor(props: IPnpReactAccordionProps) {

super(props);

this.state = {

listItems: [],

errorMessage: ''

}

/** Bind service using current context */

this._services = new SPService(this.props.context);

}

public componentDidMount() {

this.getListItems();

}

/** Get items of selected list and set values in state */

private async getListItems() {

if (this.props.listName) {

let items = await this._services.getListItems(this.props.listName);

this.setState({ listItems: items });

}

else {

this.setState({ errorMessage: 'Please enter the list name in property pane configuration.' });

}

public render(): React.ReactElement<IPnpReactAccordionProps> {

return (

{

//Map list items and render in accordion

(this.state.listItems && this.state.listItems.length) ? this.state.listItems.map((item, index) => (

</div>

</Accordion>

)) : <p>{this.state.errorMessage}</p>

}

</div>

);

}

Now serve the application using the below command,

gulp serve

1	gulp serve

Now test the webpart in SharePoint-SiteURL + /_layouts/15/workbench.aspx.
