Hello Yunsong Wang,

Currently, you cannot disable it.
You can only hide it.

Thank you for your prompt response. In the current Nevron build, is there a API can be used to disable the "Menus Options" button, other than remove the button, I think that also works for me as a workaround.

Thanks a lot.

Hello Yunsong Wang,

Currently, you cannot.

Today or tomorrow we will release a new service pack where these buttons will be hosted in FlowLayoutPanel instead in a regular Panel as it is now.
This way when you hide a button the rest of the button will be displayed nicely.

Nevron provide a method like "m_CommandBarsManager.EditorConfig.HasMenuOptionsButton = false; " to customize "Customize CommandBars", however, when set its value to false, the place where the button showed up was replaced with an empty, which make UI look kinda weird, the snapshot is attached here. Is there some way we could disable that button, other than hide it?
