# Top App Bar

> Top App Bar acts as a container for items such as application title, navigation icon, and action items.

import from **rmwc/TopAppBar**  
[https://material.io/components/web/catalog/top-app-bar/](https://material.io/components/web/catalog/top-app-bar/)

The TopAppBar cannot be effectively demoed inline, but it is in use above in the RMWC docs. To view additional functionality, check out the [Material Components Top App Bar demo page](https://material-components-web.appspot.com/top-app-bar.html).

```jsx
import {
  TopAppBar,
  TopAppBarRow,
  TopAppBarSection,
  TopAppBarNavigationIcon,
  TopAppBarActionItem,
  TopAppBarTitle
} from 'rmwc/TopAppBar';

{/* Minimum usage. material-components-web will throw an error if you do not include TopAppBarNavigationIcon. */}
<TopAppBar>
  <TopAppBarRow>
    <TopAppBarSection>
      <TopAppBarNavigationIcon use="menu" />
    </TopAppBarSection>
  </TopAppBarRow>
</TopAppBar>
