Sub menu item in Context Menu of Pro Custom Item .net sdk

[RITASHKOUL]

I have created a Pro custom item to support a new data type in Plugin Data Source. On right click I have created 2 menus. But I want to add a submenu for the second one.

<insertModule id="Addin_Module" className="Module1" autoLoad="true" caption="Module1">
<controls>
<button id="Addin_AddToCurrentMap" caption="Add To Current Map" className="AddToCurrentMap" loadOnClick="true" smallImage="pack://application:,,,/ArcGIS.Desktop.Resources;component/Images/AddLayerFromPath16.png" largeImage="pack://application:,,,/ArcGIS.Desktop.Resources;component/Images/AddLayerFromPath32.png" />
<button id="Addin_AddToNewMap" caption="Add To New Map" className="AddToNewMap" loadOnClick="true" smallImage="pack://application:,,,/ArcGIS.Desktop.Resources;component/Images/AddLayerFromPath16.png" largeImage="pack://application:,,,/ArcGIS.Desktop.Resources;component/Images/AddLayerFromPath32.png" />
</controls>
<menus>
<menu id="Addin_ProCustomItem_ContextMenu" caption="Context Menu">
<button refID="Addin_AddToCurrentMap" />
<button refID="Addin_AddToNewMap" />
</menu>
</menus>
</insertModule>

<categories>
<updateCategory refID="esri_customItems">
<insertComponent id="Addin_ProCustomItem" className="Addin.ProCustomItem">
<content displayName="pro custom item" fileExtension="abc" isContainer="false" keywords="ProCustomItem" contextMenuID="Addin_ProCustomItem_ContextMenu">
<filterFlags>
<type id="AddToMap" />
</filterFlags>
</content>
</insertComponent>
</updateCategory>
</categories>

But right now using the above code its just adding two options in the context menu. How can we make the second option a menu with submenus.

Hi,

The sample below is from @NarelleChedzey  answer in thread.

<menus>
  <menu id="esri_task_insertMenu" caption="Task" extendedCaption="Ribbon add task items menu" keytip="TA"         
         largeImage="pack://application:,,,/ArcGIS.Desktop.Resources;component/Images/TaskItem32.png"
         smallImage="pack://application:,,,/ArcGIS.Desktop.Resources;component/Images/TaskItem16.png">
    <tooltip heading="Task">Add task items to your project.</tooltip>
       <button refID="esri_tasks_NewProjectTaskItem" />
        <menu refID="esri_tasks_ImportTaskFileMenu"/>
  </menu>
  <menu id="esri_tasks_ImportTaskFileMenu" caption="Import and Open Task File"
         largeImage="pack://application:,,,/ArcGIS.Desktop.Resources;component/Images/GenericImport32.png" 
         smallImage="pack://application:,,,/ArcGIS.Desktop.Resources;component/Images/GenericImport16.png">
      <button refID="esri_tasks_ImportTaskFileBrowse"/>
      <dynamicMenu refID="esri_tasks_ImportMenu" inline="true"/>
  </menu>
 </menus>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

You can add one menu item to another menu item.
