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.

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;
