title: Add dropdown menu in a view's ToolBarManager
body: <p>I want to add several dynamically created actions to a view. This works to add them to the View Menu in the top right corner:</p>
  
  <pre><code>private void fillActionBars() {
    IActionBars bars = getViewSite().getActionBars();
    IMenuManager manager = bars.getMenuManager();
    IMenuManager myMenu = new MenuManager("Menu title", MY_MENU_ID);
    // add actions to myMenu
    manager.add(myMenu);
    bars.updateActionBars();
  }
  </code></pre>
  
  <p>This works fine. However, I want to add the actions to a dropdown menu in the toolbar instead (so the user can see them immediately). If I replace the third line with</p>
  
  <pre><code>IToolbarManager manager = bars.getToolBarManager();
  </code></pre>
  
  <p>the menu doesn't show up.</p>
