Is there any way to delete item show in navigator project map panel as shown below pict?

[Newbie]

As known this command, APINavigator_​DeleteNavigatorViewID, can delete only view map. If want to delete item from project map view, is there any command?

Use API_StoryCmdType with APIStory_Delete for this.
For Elevations, Sections and InteriorElevations I'm not sure, but I would try to delete their respective elements and see what happens.
