We present a generalization of the non-Abelian version of the CP[sup [ital N][minus]1] models (also known as Grassmannian models) that involves composite gauge fields to accommodate partial breaking of the non-Abelian gauge symmetry. For this to be possible, in many cases, the constituent fields need to belong to an anomaly-free representation. The symmetry is broken dynamically for large [ital N] primarily by a naturally generated composite scalar simulating Higgs mechanism. In the example studied in some detail, the gauge group SO(10) gets broken down to subgroups such as SU(5) or SU(5)[times]U(1).
