Appending to existing menus?

[degracode]

Is there a way that you can extend a menu that's already been created elsewhere? Quite often it's useful for sub-systems and unconnected bits of code to expose new commands etc in the main menu bar, but at the moment each call to BeginMenu() will create a new menu, rather than extending the previous instance of it.

Effectively, I want this code:

if(ImGui::BeginMenu("Test"))
{
	ImGui::MenuItem("Test Item 1");
	ImGui::EndMenu();
}

if(ImGui::BeginMenu("Test"))
{
	ImGui::MenuItem("Test Item 2");
	ImGui::EndMenu();
}

to behave as-if I'd simply done this:

if(ImGui::BeginMenu("Test"))
{
	ImGui::MenuItem("Test Item 1");
	ImGui::MenuItem("Test Item 2");
	ImGui::EndMenu();
}

however I end up with two menus, that have aliased input, and a weird clipping issue with the second item's text:

Appending doesn't work in menus yet. I forgot the exact reason right now. Would ideally want to fix it but probably not a high priority, will keep that noted though.

Will this be possible at some point in the near future?

[ocornut]

If someone tries to get it to work, yes. I have too much on my plate to be looking at it myself at the moment, hence the dangling open issue.

This is now supported thanks to commits 0342a3c and 24bd33a!

Pushed a fix where it using Left<>Right arrow to navigate within horizontally layed out item of a appended menu would erroneously close the menu (bd2355a)
