MUI or 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 will discuss the React MUI TabPanel API. The Tabs are used to make navigation easier and more useful. We can easily switch between the views. The TabContext is used to hold the index of the current tab. The API provides a lot of functionality and we will learn to implement them.
Import TabContext API:
import TabContext from '@mui/lab/TabContext';
// or
import { TabContext } 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 (node): It is a component similar to the table row.
- value(string): The currently selected tab index value.
Syntax: Use the TabContext in Tabs as follows:
<TabContext value={value}>
...
</TabContext>
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 TabContext with Tabs inside.
App.js
import "./App.css" ;
import * as React from "react" ;
import Box from "@mui/material/Box" ;
import Tab from "@mui/material/Tab" ;
import TabContext from "@mui/lab/TabContext" ;
import TabList from "@mui/lab/TabList" ;
import TabPanel from "@mui/lab/TabPanel" ;
function App() {
const [value, setValue] = React.useState( "1" );
const handleChange = (event, newValue) => {
setValue(newValue);
};
return (
<div className= "App" >
<div
className= "head"
style={{
width: "fit-content" ,
margin: "auto" ,
}}
>
<h1
style={{
color: "green" ,
}}
>
GeeksforGeeks
</h1>
</div>
<div
style={{
width: "fit-content" ,
margin: "auto" ,
}}
>
<strong>React MUI TabContext API</strong>
</div>
<br />
<div
style={{
margin: "auto" ,
display: "flex" ,
justifyContent: "space-evenly" ,
}}
>
<Box sx={{ width: "100%" , typography: "body1" }}>
<TabContext value={value}>
<Box sx={{ borderBottom: 1, borderColor: "divider" }}>
<TabList onChange={handleChange}>
<Tab label= "Tutorial 1" value= "1" />
<Tab label= "Tutorial 2" value= "2" />
<Tab label= "Tutorial 3" value= "3" />
</TabList>
</Box>
<TabPanel value= "1" >Data Structures</TabPanel>
<TabPanel value= "2" >Algorithms</TabPanel>
<TabPanel value= "3" >Web Development</TabPanel>
</TabContext>
</Box>
</div>
</div>
);
}
export default App;
|
Output:
Example 2: In the following example, we will be modifying the value provided in the TabContext using mod 3 +1 so that a different tab is selected.
App.js
import "./App.css" ;
import * as React from "react" ;
import Box from "@mui/material/Box" ;
import Tab from "@mui/material/Tab" ;
import TabContext from "@mui/lab/TabContext" ;
import TabList from "@mui/lab/TabList" ;
import TabPanel from "@mui/lab/TabPanel" ;
function App() {
const [value, setValue] = React.useState( "1" );
const handleChange = (event, newValue) => {
setValue(newValue);
};
return (
<div className= "App" >
<div
className= "head"
style={{
width: "fit-content" ,
margin: "auto" ,
}}
>
<h1
style={{
color: "green" ,
}}
>

</div>
<div
style={{
width: "fit-content" ,
margin: "auto" ,
}}

<div
style={{
margin: "auto" ,
display: "flex" ,
justifyContent: "space-evenly" ,
}}
>
<Box sx={{ width: "100%" , typography: "body1" }}>
<TabContext value={((parseInt(value) % 3) + 1).toString()}>
<Box sx={{ borderBottom: 1, borderColor: "divider" }}>
<TabList onChange={handleChange}>
<Tab label= "Tutorial 1" value= "1" />
<Tab label= "Tutorial 2" value= "2" />
<Tab label= "Tutorial 3" value= "3" />
</TabList>
</Box>
<TabPanel value= "1" >Data Structures</TabPanel>
<TabPanel value= "2" >Algorithms</TabPanel>
<TabPanel value= "3" >Web Development</TabPanel>
</TabContext>
</Box>
</div>
</div>
);
}
export default App;
