Allow Submenus in Context Menu

[oprobst88]

Hi

I really like working with the Monaco Editor. I use it in a react app. I've started to use the context menu and using the addAction(descriptor: IActionDescriptor): IDisposable method to add customized entries. It would be really great to be able to add submenus. Otherwise, the context menu gets a bit messy...

Thanks Oliver

[umesh-timalsina]

This would really help. Is there a possibility to add a submenu?

Did you finally achieve it? I also wanted this feature, I tried to modify the source code to achieve the effect but it was difficult for me to introduce that many dependencies outside to achieve the effect of this feature. And if you did, can you tell me what you did in the end

[oprobst88]

No. In the meantime I've switched to another editor.

Is there a reason you closed this? I still think this is very much an issue I'd like to see resolved.

Its weird because VSCode has nested context menus.

[sukh1495]

is there any update or any code snippet which can help to add sub actions for a action here like Peek in VS editor or monaco editor playground?

[minzhenyu]

@alexdima Is there a development plan for this feature?

[dh666]

I like the default contextmenu of monaco-editor,I want to customize it.But I can't define the submenu by the method addAction. I'm not sure whether I can use the precondition, Do you have any solutions?

@hediet Is this issues achievable？
