title: Create a sub menu in existing menu in Excel Shared Add-in
body: <p>I am developing a Excel shared Add-in which has the menu called <code>Custom</code> which is created using Excel Macros. Now i want to create a submenu under the <code>Custom</code> menu using Csharp Shared Add -in. Iam using the below code for doing this but no help</p>
  
  <pre><code>oStandardBar = oCommandBars["Custom"];
  oCmdBarCtrl = oStandardBar.Controls.Add(MsoControlType.msoControlPopup, Type.Missing, Type.Missing, Type.Missing, true);
  oCmdBarCtrl.Visible = false;
  oCmdBarCtrl.Caption = "Sub Menu1";
  </code></pre>
  
  <p>But it does not create a submenu, where as if i give "Help" in place of Custom i get the menu created. any work around for this?</p>
