-      <core-submenu icon="settings" label="Topics">
-        <core-item label="Topic 1"></core-item>
-        <core-item label="Topic 2"></core-item>
-      </core-submenu>

-        <core-item label="Favorite 2"></core-item>
-        <core-item label="Favorite 3"></core-item>
-      </core-submenu>
-      
-    </core-menu>

-There is a margin set on the submenu to indent the items.
-You can override the margin by doing:
-
-    core-submenu::shadow #submenu {
-      margin-left: 20px;
-    }
