# BrowserBar
A navigation bar designed for browser-like interfaces, featuring slots for start, end, and central content. It provides a structured layout for controls and information within a browser context.
## Import
```tsx
import { BrowserBar } from '@coinbase/cds-mobile/navigation/BrowserBar'
```
## Examples
### Basic usage
A `BrowserBar` can be used to display information and actions, like in a web browser.
```tsx
}
end={}
>
Coinbase
```
### With Search Input
A common use case is to include a search or URL input field.
```tsx
}
end={
}
>
```
### Contextual Hiding
`BrowserBar` provides a `BrowserBarContext`. Components rendered inside the `BrowserBar` can use the `useBrowserBarContext` hook to gain access to `setHideStart` and `setHideEnd` functions. These functions allow children components to dynamically hide the `start` and `end` content of the `BrowserBar`, which can be useful to maximize space for the primary content.
