React MUI TimelineSeparator 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 TimelineSeparator API. The TimelineSeparator is the line between two Timeline Item that forms the line in the Timeline and the items appear either left or right of it. Also, the TimelineDot appears on it. The API provides a lot of functionality and we are going to learn to implement them.

Import TimelineSeparator API

import TimelineSeparator from '@mui/lab/TimelineSeparator';
// or
import { TimelineSeparator } 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 TimelineSeparator component as follows:

<TimelineItem>
    <TimelineSeparator>
        <TimelineDot color="success" />
    </TimelineSeparator>
    <TimelineContent>Javascript</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 with TimelineSeparators between timeline items.

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",
          }}
        >

        </h1>
        <strong>React MUI TimelineSeparator API</strong>
      </div>

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

export default App;

Output:

Example 2: In the following example, we have customized the TimelineSeparator components using the sx attribute.

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 TimelineSeparator API</strong>
      </div>

      <Timeline>
        <TimelineItem position="left">
          <TimelineSeparator
            sx={{
              backgroundColor: "green",
              opacity: 0.5,
            }}
          >
            <TimelineDot />
            <TimelineConnector />
          </TimelineSeparator>
          <TimelineContent>Frontend Learning Path</TimelineContent>
        </TimelineItem>
        <TimelineItem>
          <TimelineSeparator
            sx={{
              backgroundColor: "green",
              opacity: 0.5,
            }}
          >
            <TimelineDot />
            <TimelineConnector />
          </TimelineSeparator>
          <TimelineContent>HTML</TimelineContent>
        </TimelineItem>
        <TimelineItem>
          <TimelineSeparator
            sx={{
              backgroundColor: "green",
              opacity: 0.5,
            }}
          >
            <TimelineDot />
            <TimelineConnector />
          </TimelineSeparator>
          <TimelineContent>CSS</TimelineContent>
        </TimelineItem>
        <TimelineItem>
          <TimelineSeparator
            sx={{
              backgroundColor: "green",
              opacity: 0.5,
            }}
          >
            <TimelineDot />
          </TimelineSeparator>
          <TimelineContent>Javascript</TimelineContent>
        </TimelineItem>
      </Timeline>
