title: Android ActionBar menu items scrollable
body: <p>I have many sub items under one item in the action bar. Rather than take up the whole page,  How would I make the drop down list scrollable to conserve space? </p>
  
  <p>This is the menu item </p>
  
  <pre><code>  &lt;menu xmlns:android="http://schemas.android.com/apk/res/android" &gt;
  
      &lt;item
          android:icon="@drawable/ic_action_search"
          android:showAsAction="ifRoom"&gt;
          &lt;menu&gt;
              &lt;item
                  android:id="@+id/airport"
                  android:showAsAction="always|withText"
                  android:title="Airport"/&gt;
              &lt;item
                  android:id="@+id/atm"
                  android:showAsAction="always|withText"
                  android:title="Atm"/&gt;
              &lt;item
                  android:id="@+id/bank"
                  android:showAsAction="always|withText"
                  android:title="Bank"/&gt;
