<MdcTopAppBar @fixed=[true|false] 
              @dense=[true|false]
              @prominent=[true|false]
              @short=[true|false]

              @navigation={{this.navigation}}>
  <MdcTopAppBarRow>
  
  </MdcTopAppBarRow>
</MdcTopAppBar>

Attributes

• fixed - The top app bar is fixed to the top of the page.
• dense - The top app bar is shorter.
• prominent - The top app bar is taller.
• short - The top app bar can collapse to the navigation icon side when scrolled.
• alwaysCollapsed - The top app bar always appears collapsed (when short).

Adding sections to a row

The <MdcTopAppBar> component can contain sections. The sections can either be aligned to the start or end of the <MdcTopAppBarRow>. There is no default alignment.

<MdcTopAppBar @fixed={{true}}>
  <MdcTopAppBarRow>
    <MdcTopAppBarSection @position="alignStart">
    
    </MdcTopAppBarSection>
  
    <MdcTopAppBarSection @position="alignEnd">
      
    </MdcTopAppBarSection>
  </MdcTopAppBarRow>
</MdcTopAppBar>

Adding a title to the app bar

Use the <MdcTopAppBarTitle> component to add a title to the top app bar.

<MdcTopAppBar @fixed={{true}}>
  <MdcTopAppBarRow>
    <MdcTopAppBarSection @position="alignStart">
      <MdcTopAppBarTitle>Ember Material</MdcTopAppBarTitle>
    </MdcTopAppBarSection>
  
    <MdcTopAppBarSection @position="alignEnd">
      
    </MdcTopAppBarSection>

  </MdcTopAppBarRow>
</MdcTopAppBar>

The navigation icon

The <MdcTopAppBarNavigationIcon> is used to add a navigation icon to the top app bar. Likewise, the @navigation attribute on <MdcTopAppBar> is invoked when the navigation icon is clicked.

<MdcTopAppBar @fixed={{true}} @navigation={{this.openDrawer}}>
  <MdcTopAppBarRow>
    <MdcTopAppBarSection @position="alignStart">
      <MdcTopAppBarNavigationIcon @icon="menu" />
      <MdcTopAppBarTitle>Ember Material</MdcTopAppBarTitle>
    </MdcTopAppBarSection>
  
    <MdcTopAppBarSection @position="alignEnd">
      
    </MdcTopAppBarSection>

  </MdcTopAppBarRow>
</MdcTopAppBar>

The <MdcTopAppBarNavigateUpTo> component adds the navigate up icon to the top app bar. It also allows you to link to a page in the application.

<MdcTopAppBar @fixed={{true}}>
  <MdcTopAppBarRow>
    <MdcTopAppBarSection @position="alignStart">
      <MdcTopAppBarNavigateUpTo @route="index" />
      <MdcTopAppBarTitle>Ember Material</MdcTopAppBarTitle>
    </MdcTopAppBarSection>
  
    <MdcTopAppBarSection @position="alignEnd">
      
    </MdcTopAppBarSection>

  </MdcTopAppBarRow>
</MdcTopAppBar>

Adding action items to the top app bar

Action items usually appear at the end of the action bar. The <MdcTopAppBarActionItem> components adds an action item to the top app bar.

<MdcTopAppBar @fixed={{true}}>
  <MdcTopAppBarRow>
    <MdcTopAppBarSection @position="alignStart">
      <MdcTopAppBarNavigateUpTo @route="index" />
      <MdcTopAppBarTitle>Ember Material</MdcTopAppBarTitle>
    </MdcTopAppBarSection>
  
    <MdcTopAppBarSection @position="alignEnd">
      <MdcTopAppBarActionItem @label="Download" @icon="file_download" alt="Download" />
    </MdcTopAppBarSection>
  </MdcTopAppBarRow>
</MdcTopAppBar>

The <MdcTopAppBarActionItem> supports the following attributes:

• icon - The icon for the action item.
• label - The accessibility label for the action item (optional).

mdc-top-app-bar-fixed-adjustment

      <MdcTopAppBarActionItem @label="Download" @icon="file_download" alt="Download" />
    </MdcTopAppBarSection>
  </MdcTopAppBarRow>
</MdcTopAppBar>

<div {{mdc-top-app-bar-fixed-adjustment dense=this.dense 
                                        short=this.short
