```js
import BottomNavigationAction from '@material-ui/core/BottomNavigationAction';
```



## Props

| Name | Type | Default | Description |
|:-----|:-----|:--------|:------------|
| <span class="prop-name">children</span> | <span class="prop-type">unsupportedProp |   | This property isn't supported. Use the `component` property if you need to change the children structure. |
| <span class="prop-name">classes</span> | <span class="prop-type">object |   | Override or extend the styles applied to the component. See [CSS API](#css-api) below for more details. |
| <span class="prop-name">icon</span> | <span class="prop-type">node |   | The icon element. |
| <span class="prop-name">label</span> | <span class="prop-type">node |   | The label element. |
| <span class="prop-name">showLabel</span> | <span class="prop-type">bool |   | If `true`, the `BottomNavigationAction` will show its label. By default, only the selected `BottomNavigationAction` inside `BottomNavigation` will show its label. |
| <span class="prop-name">value</span> | <span class="prop-type">any |   | You can provide your own value. Otherwise, we fallback to the child position index. |

Any other properties supplied will be spread to the root element ([ButtonBase](/api/button-base/)).

## CSS API

You can override all the class names injected by Material-UI thanks to the `classes` property.
This property accepts the following keys:


| Name | Description |
|:-----|:------------|
| <span class="prop-name">root</span> | Styles applied to the root element.
| <span class="prop-name">selected</span> | Styles applied to the root element if selected.
| <span class="prop-name">iconOnly</span> | Styles applied to the root element if `showLabel={false}` and not selected.
| <span class="prop-name">wrapper</span> | Styles applied to the span element that wraps the icon and label.
| <span class="prop-name">label</span> | Styles applied to the label's span element.

Have a look at [overriding with classes](/customization/overrides/#overriding-with-classes) section
and the [implementation of the component](https://github.com/mui-org/material-ui/tree/master/packages/material-ui/src/BottomNavigationAction/BottomNavigationAction.js)
for more detail.

If using the `overrides` key of the theme as documented
[here](/customization/themes/#customizing-all-instances-of-a-component-type),
you need to use the following style sheet name: `MuiBottomNavigationAction`.

## Inheritance

The properties of the [ButtonBase](/api/button-base/) component are also available.
You can take advantage of this behavior to [target nested components](/guides/api/#spread).
