Android Lollipop, add popup menu from title in toolbar

Question

I'm unable to see how adding a popup menu from the title is accomplished like is shown in many of the material design examples. Any help would be much appreciated.

You're going to need to add a Spinner to the Toolbar:

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_height="?attr/actionBarSize"
        android:layout_width="match_parent"
        android:background="?attr/colorPrimary">

    <Spinner
            android:id="@+id/spinner_nav"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

</android.support.v7.widget.Toolbar>

You will then need to disable the default title:

Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);

You can then retrieve and setup the Spinner as needed in your Activity/Fragment.
