The Bottom Navigation bar allows movement between primary destinations in an app.
Bottom navigation bars display three to five destinations at the bottom of a screen. Each destination is represented by an icon and an optional text label. When a bottom navigation icon is tapped, the user is taken to the top-level navigation destination associated with that icon.
When there are only three actions, display both icons and text labels at all times.
import * as React from 'react';
import Box from '@mui/material/Box';
import BottomNavigation from '@mui/material/BottomNavigation';
import BottomNavigationAction from '@mui/material/BottomNavigationAction';
import RestoreIcon from '@mui/icons-material/Restore';
import FavoriteIcon from '@mui/icons-material/Favorite';
import LocationOnIcon from '@mui/icons-material/LocationOn';
export default function SimpleBottomNavigation() {
const [value, setValue] = React.useState(0);
return (
<Box sx={{ width: 500 }}>
<BottomNavigation
showLabels
value={value}
onChange={(event, newValue) => {
setValue(newValue);
}}
>
<BottomNavigationAction label="Recents" icon={<RestoreIcon />} />
<BottomNavigationAction label="Favorites" icon={<FavoriteIcon />} />
<BottomNavigationAction label="Nearby" icon={<LocationOnIcon />} />
</BottomNavigation>
</Box>
);
}
If there are four or five actions, display inactive views as icons only.
import * as React from 'react';
import BottomNavigation from '@mui/material/BottomNavigation';
import BottomNavigationAction from '@mui/material/BottomNavigationAction';
import FolderIcon from '@mui/icons-material/Folder';
import RestoreIcon from '@mui/icons-material/Restore';
import FavoriteIcon from '@mui/icons-material/Favorite';
import LocationOnIcon from '@mui/icons-material/LocationOn';
export default function LabelBottomNavigation() {
const [value, setValue] = React.useState('recents');
const handleChange = (event: React.SyntheticEvent, newValue: string) => {
setValue(newValue);
};
return (
<BottomNavigation sx={{ width: 500 }} value={value} onChange={handleChange}>
<BottomNavigationAction
label="Recents"
value="recents"
icon={<RestoreIcon />}
/>
<BottomNavigationAction
label="Favorites"
value="favorites"
icon={<FavoriteIcon />}
/>
<BottomNavigationAction
label="Nearby"
value="nearby"
icon={<LocationOnIcon />}
/>
<BottomNavigationAction label="Folder" value="folder" icon={<FolderIcon />} />
</BottomNavigation>
);
}
This demo keeps bottom navigation fixed to the bottom, no matter the amount of content on-screen.

One frequent use case is to perform navigation on the client only, without an HTTP round-trip to the server.
The BottomNavigationAction
component provides the component
prop to handle this use case.
