Icons

Use of Material Icon's for Action Items and Navigation Icons are recommended, since the Ripple is included with the Component. Using custom Components will require you to wrap the Component with the withRipple HOC. If you do decide to build your own custom Component, it is recommended to use the hasRipple prop to toggle between icons with and without ripple. See the Material Icon's implementation to see how to implement the hasRipple prop within your custom Component.

Navigation Icon

The navigation icon can be a <a>, <i>, <svg>, <image>, <span>, etc., but again must be wrapped with the withRipple HOC.

  <TopAppBarIcon navIcon>
    <i className='material-icons'>menu</i>
  </TopAppBarIcon>

If you decide to use a React Component please see Integrating with Components.

Action Items

Similar to the navigation icon, it can be <a>, <i>, <svg>, <image>, <span>, etc., and must be wrapped with the withRipple HOC.

  <TopAppBarIcon actionItem>
    <i className='material-icons'>bookmark</i>
  </TopAppBarIcon>

If you decide to use a React Component please see Integrating with Components.

Sass Mixins

Sass mixins may be available to customize various aspects of the Components. Please refer to the MDC Web repository for more information on what mixins are available, and how to use them.
