Creating Dynamic Accordion Control using PnP SPFx Controls React

In this article, I have explained how to create a dynamic accordion control from SharePoint List using PnP SPFx controls react and PNP JS.

Before creating the application, add a SharePoint list named "Accordion" in your SharePoint Site.

Column Name	DataType
Title	Single line of text
Description	Multiline of text

Create a SPFx project, "Dynamic Accordion" using "React" Template

Dynamic Accordion control using pnp SPFx controls react

Install necessary NPM Packages

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

Open the "DynamicAccordion.tsx" file and import the accordion control from PnP SPFx controls react and pnp/sp to interact With SharePoint API

JavaScript

import { SPFI } from '@pnp/sp';

Create the interface to store the items in the React state

JavaScript

export interface AccordionState {
  Items: any[]
}

Initialize the constructor and state from the props

JavaScript

 private _sp: SPFI;
  constructor(props: IDynamicAccordionProps) {
    super(props)
    this.state = { Items: [] };
    this._sp = getSP();
  }

Create a private method "async" method to fetch the items from the SharePoint list "GetItems()" and set it into react state

Load the "GetItems() in the "ComponentDidMount()"

JavaScript

  componentDidMount(): void {
    this.GetItems();
  }

Now I am going to create a child component, "AccordionContent.tsx" to manage the accordion control and send the data over props to display in the child component.

Import the necessary NPM package from @pnp/spfx-controls react & create an interface to hold the data props.

JavaScript

import { Accordion } from '@pnp/spfx-controls-react';
export interface IItemprops {
    data: any[]
}

Initialize the constructor in child components and pass the IItemprops.

Inside the render method, use the let keyword to initialize the variable "Items" and set the data props like the below snippet.

JavaScript

  public render(): React.ReactElement<IItemprops> {
        let items = this.props.data
        if (this.props.data != null) {
            return (<div>
                <h1>Dynamic Accordion Control</h1>
                {items.map((item, index) => (
                    <Accordion title={item.Title} defaultCollapsed={true} expandedIcon={"ChevronUp"} collapsedIcon={"ChevronDown"} className={"itemCell"} key={index}>
                        <div className={"itemContent"}>
                            <div className={"itemResponse"}>{item.Description}</div>
                            <div className={"itemIndex"}>{`Langue :  ${item.Title}`}</div>
                        </div>
                    </Accordion>
                ))}
            </div>)
        } else {
            return (
                <p>No Items Found !....</p>
            )
        }
    }

The full code of "AccordionContent.tsx" look like below.

JavaScript

import * as React from 'react';
import { Accordion } from '@pnp/spfx-controls-react';
export interface IItemprops {
    data: any[]
}

export class AccordionContent extends React.Component<IItemprops> {

    constructor(props: IItemprops) {
        super(props)
    }
    public render(): React.ReactElement<IItemprops> {
        let items = this.props.data
        if (this.props.data != null) {
            return (<div>
                <h1>Dynamic Accordion Control</h1>
                {items.map((item, index) => (
                    <Accordion title={item.Title} defaultCollapsed={true} expandedIcon={"ChevronUp"} collapsedIcon={"ChevronDown"} className={"itemCell"} key={index}>
                        <div className={"itemContent"}>
                            <div className={"itemResponse"}>{item.Description}</div>
                            <div className={"itemIndex"}>{`Langue :  ${item.Title}`}</div>
                        </div>
                    </Accordion>
                ))}
            </div>)
        } else {
            return (
                <p>No Items Found !....</p>
            )
        }
    }
}

Finally, the full code like below in the "DynamicAccorion.tsx" file

JavaScript

import * as React from 'react';
import { useEffect } from 'react';
import styles from './DynamicAccordion.module.scss';
import { IDynamicAccordionProps } from './IDynamicAccordionProps';
import { escape } from '@microsoft/sp-lodash-subset';

import { AccordionContent } from "./AccordionContent";
import { SPFI } from '@pnp/sp';
import { getSP } from '../../config';
import { Async } from 'office-ui-fabric-react';
export interface AccordionState {
  Items: any[]
}

export default class DynamicAccordion extends React.Component<IDynamicAccordionProps, AccordionState> {
  private _sp: SPFI;
  constructor(props: IDynamicAccordionProps) {
    super(props)
    this.state = { Items: [] };
    this._sp = getSP();
  }

  private async GetItems() {
    let items = await this._sp.web.lists.getByTitle('Accordion').items()
    if (items.length > 0) {
      this.setState({
        Items: items
      });
    }
  }

  componentDidMount(): void {
    this.GetItems();
  }


  public render(): React.ReactElement<IDynamicAccordionProps> {
    let sampleItems = (this.state.Items.length > 0) ? this.state.Items : null;
    return (
      <AccordionContent data={sampleItems} ></AccordionContent>
    )
  }
}

Execute "Gulp Serve" from your Visual Studio code terminal to load the SharePoint site workbench.
