// BeginListBox() is essentially a thin wrapper to using BeginChild()/EndChild() with the ImGuiChildFlags_FrameStyle flag for stylistic changes + displaying a label.
// You may be tempted to simply use BeginChild() directly, however note that BeginChild() requires EndChild() to always be called (inconsistent with BeginListBox()/EndListBox()).

// Using the generic BeginListBox() API, you have full control over how to display the combo contents.
