  We construct multi-soliton solutions of the n-component vector nonlinear
Schr\"odinger equation on the half-line subject to two classes of integrable
boundary conditions (BCs): the homogeneous Robin BCs and the mixed
Neumann/Dirichlet BCs. The construction is based on the approach of dressing
the integrable BCs: soliton solutions are generated in preserving the
integrable BCs at each step of the Darboux-dressing process. Under the Robin
BCs, examples, including boundary-bound solitons, are explicitly derived; under
the mixed Neumann/Dirichlet BCs, the boundary can act as a polarizer that tunes
different components of the vector solitons.
