I am trying to find out how can I add a new menu to the study browser and put submenus with click actions inside, can anyone help me please?

I added the menu by StudyBrowserToolExtensionPoint but how can I add submenus with actions to it?

There is a method in ImageViewer Tools by ImageViewerToolExtensionPoint but does not work, can anyone provide an example?

thank you

 Have a look at the action attributes on CopyToClipboardTool (below): you can decorate the same tool with multiple action attributes on the same path.

    [MenuAction("copyImage", "imageviewer-contextmenu/MenuClipboard/MenuCopyImageToClipboard", "CopyImage")]
    [MenuAction("copyImage", ShowClipboardTool.ClipboardToolbarDropdownSite + "/MenuCopyImageToClipboard", "CopyImage")]
    [IconSet("copyImage", IconScheme.Colour, "Icons.CopyToClipboardToolSmall.png", "Icons.CopyToClipboardToolMedium.png", "Icons.CopyToClipboardToolLarge.png")]
    [EnabledStateObserver("copyImage", "CopyImageEnabled", "CopyImageEnabledChanged")]

    [MenuAction("copyDisplaySet", "imageviewer-contextmenu/MenuClipboard/MenuCopyDisplaySetToClipboard", "CopyDisplaySet")]
    [MenuAction("copyDisplaySet", ShowClipboardTool.ClipboardToolbarDropdownSite + "/MenuCopyDisplaySetToClipboard", "CopyDisplaySet")]
    [IconSet("copyDisplaySet", IconScheme.Colour, "Icons.CopyToClipboardToolSmall.png", "Icons.CopyToClipboardToolMedium.png", "Icons.CopyToClipboardToolLarge.png")]
    [EnabledStateObserver("copyDisplaySet", "CopyDisplaySetEnabled", "CopyDisplaySetEnabledChanged")]

    [MenuAction("copySubset", "imageviewer-contextmenu/MenuClipboard/MenuCopySubsetToClipboard", "CopySubset")]
    [MenuAction("copySubset", ShowClipboardTool.ClipboardToolbarDropdownSite + "/MenuCopySubsetToClipboard", "CopySubset")]
    [IconSet("copySubset", IconScheme.Colour, "Icons.CopyToClipboardToolSmall.png", "Icons.CopyToClipboardToolMedium.png", "Icons.CopyToClipboardToolLarge.png")]
    [EnabledStateObserver("copySubset", "CopySubsetEnabled", "CopySubsetEnabledChanged")]
