ReactJS Blueprint Collapsible List Component

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;
