== Using the helper

If the helper is called without passing in the type, it will render the default menu using the default view partials.

Example:

<%= partial_menu %>

… will result in menu.yaml getting displayed using partials from app/views/partial_menu:

<ul>
  <li><a href="/">First item</a></li>
  ...
</ul>

Any options defined in the call will be send to render as local variables

Example:

<%= partial_menu 'menu', {menu_id:'sidemenu'} %>

You can leave out menu type parameter:

Example:

<%= partial_menu {menu_id:'sidemenu'} %>
