React MUI TimelineContent API

Material-UI is a UI library providing predefined robust and customizable components for React for easier web development. The MUI design is based on top of Material Design by Google. 

In this article, we are going to discuss the React MUI TimelineContent API. The TimelineContent contains the element content that is placed in the Timeline. The API provides a lot of functionality and we are going to learn to implement them.

Import TimelineContent API

import TimelineContent from '@mui/lab/TimelineContent';
// or
import { TimelineContent } from '@mui/lab';

Props List: Here is the list of different props used with this component. We can access them and modify them according to our needs.

• children: It is a component similar to the table row.
• classes: This overrides the existing styles or adds new styles to the component.
• sx: The system prop allows defining system overrides as well as additional CSS styles. 

Syntax: Create the TimelineContent item as follows:

<TimelineItem>
    <TimelineSeparator>
        <TimelineDot color="success" />
    </TimelineSeparator>
    <TimelineContent>Welcome</TimelineContent>
</TimelineItem>

Installing and Creating React app, and adding the MUI dependencies.

Step 1: Create a react project using the following command.

npx create-react-app gfg_tutorial

Step 2: Get into the project directory

cd gfg_tutorial

Step 3: Install the MUI dependencies as follows:

npm install @mui/material @emotion/react @emotion/styled @mui/lab

Step 4: Run the project as follows:

npm start

Example 1: In the following example, we have a timeline tree with timeline items containing the TimelineContent component.

App.js

import "./App.css";
import Timeline from "@mui/lab/Timeline";
import TimelineItem from "@mui/lab/TimelineItem";
import TimelineSeparator from "@mui/lab/TimelineSeparator";
import TimelineConnector from "@mui/lab/TimelineConnector";
import TimelineContent from "@mui/lab/TimelineContent";
import TimelineDot from "@mui/lab/TimelineDot";
function App() {
  return (
    <div className="App">
      <div
        className="head"
        style={{
          width: "fit-content",
          margin: "auto",
        }}
      >
        <h1
          style={{
            color: "green",
          }}
        >
          GeeksforGeeks
        </h1>
        <strong>React MUI TimelineContent API</strong>
      </div>

      <Timeline>
        <TimelineItem position="left">
          <TimelineSeparator>
            <TimelineDot color="error" />
            <TimelineConnector />
          </TimelineSeparator>
          <TimelineContent>Frontend Learning Path</TimelineContent>
        </TimelineItem>
        <TimelineItem>
          <TimelineSeparator>
            <TimelineDot color="primary" />
            <TimelineConnector />
          </TimelineSeparator>
          <TimelineContent>HTML</TimelineContent>
        </TimelineItem>
        <TimelineItem>
          <TimelineSeparator>
            <TimelineDot color="warning" />
            <TimelineConnector />
          </TimelineSeparator>
          <TimelineContent>CSS</TimelineContent>
        </TimelineItem>
        <TimelineItem>
          <TimelineSeparator>
            <TimelineDot color="success" />
          </TimelineSeparator>
          <TimelineContent>Javascript</TimelineContent>
        </TimelineItem>
      </Timeline>
    </div>
  );
}

export default App;

Output:

Example 2: In the following example, we have used the sx to override the default CSS and then applied new CSS on the first TimelineContent component.

App.js

import "./App.css";
import Timeline from "@mui/lab/Timeline";
import TimelineItem from "@mui/lab/TimelineItem";
import TimelineSeparator from "@mui/lab/TimelineSeparator";
import TimelineConnector from "@mui/lab/TimelineConnector";
import TimelineContent from "@mui/lab/TimelineContent";
import TimelineDot from "@mui/lab/TimelineDot";
function App() {
  return (
    <div className="App">
      <div
        className="head"
        style={{
          width: "fit-content",
          margin: "auto",
        }}
      >
        <h1
          style={{
            color: "green",
          }}
        >
          GeeksforGeeks
        </h1>
        <strong>React MUI TimelineContent API</strong>
      </div>

      <Timeline>
        <TimelineItem position="left">
          <TimelineSeparator>
            <TimelineDot color="error" />
            <TimelineConnector />
          </TimelineSeparator>
          <TimelineContent>Frontend Learning Path</TimelineContent>
        </TimelineItem>
        <TimelineItem>
          <TimelineSeparator>
            <TimelineDot color="primary" />
            <TimelineConnector />
          </TimelineSeparator>
          <TimelineContent
            sx={{
              color: "blue",
              fontWeight: "bold",
              textDecoration: "underline",
            }}
          >
            HTML
          </TimelineContent>
        </TimelineItem>
        <TimelineItem>
          <TimelineSeparator>
            <TimelineDot color="warning" />
            <TimelineConnector />
          </TimelineSeparator>
          <TimelineContent
            sx={{
              color: "orange",
              fontWeight: "bold",
              textDecoration: "underline",
            }}
          >
            CSS
          </TimelineContent>
        </TimelineItem>
        <TimelineItem>
          <TimelineSeparator>
            <TimelineDot color="success" />
          </TimelineSeparator>
          <TimelineContent
            sx={{
              color: "green",
              fontWeight: "bold",
              textDecoration: "underline",
            }}
          >
            Javascript
          </TimelineContent>
        </TimelineItem>
      </Timeline>
    </div>
  );
}

export default App;
