  We explore a system composed of scalar bosons and SU($3$) fermions in one
dimension. Considering only local intra- and interspecies interactions, the
system is described by the Bose-Fermi-Hubbard Hamiltonian, which is studied
using the density matrix renormalization group method. In addition to the
common gapless and mixed Mott insulator phases, we identify unknown gapped
states, in which bosons couple with some or all flavors of fermions. We unveil
different flavor-selective states characterized by itinerant fermions that
coexist with an insulator state where the bosons tie with only one- or
two-flavor fermions. The states reported here could be implemented in
cold-atoms experiments.
