Polarisation structure of complex propagating beams can be designed to exhibit controlled configurations which can be described via hopfion quasiparticles. This family of polarisation textures can be described from basic topological theories and realised experimentally. The topological hopfion numbers can be additionally tuned revealing higher-order hopfions. The hopfion can be further transported by tuning phases of the constituting beams forming a hopfion.
