A grid mounting system for a suspended ceiling system in one embodiment includes a support structure and a mounting bracket coupled to the support structure. An elongated first grid member is pivotably coupled to the mounting bracket about a pivot axis defined by a pivot member. The first grid member is movable about the pivot axis in a plurality of angular mounting positions. In one embodiment, the grid mounting system further includes a second grid member which may be pivotably or fixedly coupled to the mounting bracket. The support structure may be a wall or perimeter trim bracket attached to the wall in some installations.
