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.

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; |
