ReactJS Blueprint Collapsible List Component

Last Updated : 08 Apr, 2022

BlueprintJS is a React-based UI toolkit for the web. This library is very optimized and popular for building interfaces that are complex data-dense for desktop applications.

CollapsibleList Component provides a way for users to shows precisely the passed many items and collapses the rest into a dropdown menu. We can use the following approach in ReactJS to use the ReactJS Blueprint CollapsibleList Component.

CollapsibleList Props:

className: It is used to denote a space-delimited list of class names to pass along to a child element.
collapseFrom: It is used to denote which direction the items should collapse from i.e the start or end of the children.
dropdownProps: It used to denote the props to pass to the dropdown.
dropdownTarget: It is used to denote an element to render as a dropdown target with CLICK interaction to show collapsed menu.
visibleItemClassName: It is used to denote CSS class name to add to <li> tags containing each visible item and the dropdown.
visibleItemCount: It is used to denote an exact number of visible items.
visibleItemRenderer: It is used to denote a Callback invoked to render each visible item.

Creating React Application And Installing Module:

Step 1: Create a React application using the following command:
```
npx create-react-app foldername
```
Step 2: After creating your project folder i.e. foldername, move to it using the following command:
```
cd foldername
```
Step 3: After creating the ReactJS application, Install the required module using the following command:
```
npm install @blueprintjs/core
```

Project Structure: It will look like the following.

Project Structure

Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

App.js

import React from 'react'
import '@blueprintjs/core/lib/css/blueprint.css'; 
import { CollapsibleList, MenuItem, Classes } from "@blueprintjs/core"; 
  
function App() { 
  
    return ( 
        <div style={{ 
            display: 'block', width: 400, padding: 30 
        }}> 
            <h4>ReactJS Blueprint CollapsibleList Component</h4> 
            <CollapsibleList 
                className={Classes.BREADCRUMBS} 
                dropdownTarget={<span className={Classes.BREADCRUMBS_COLLAPSED} />} 
                visibleItemRenderer={() => {}} 
            > 
                <MenuItem icon="folder-close" text="Documents" href="#" /> 
                <MenuItem icon="folder-close" text="List Item" href="#" /> 
                <MenuItem icon="folder-close" text="User Login" href="#" /> 
                <MenuItem icon="folder-close" text="Jobs" href="#" /> 
                <MenuItem icon="folder-close" text="Daylight" href="#" /> 
                <MenuItem icon="document" text="How to crush it" /> 
            </CollapsibleList> 
        </div > 
    ); 
} 
  
export default App;
