  We put forward a new method of constructing unfolded formulations of field
theories, which is based on initial fixation of the form of an unfolded field
and subsequent looking for the corresponding unfolded equation as an identity
that this field satisfies. Making use of this method, we find an unfolded
formulation for 4d scalar electrodynamics. By considering a symmetry-breaking
scalar potential, we study the implementation of the Higgs mechanism within the
framework of the unfolded dynamics approach. We explore a deformation of
unfolded modules in the symmetry-broken phase and identify a non-invertible
unfolded field redefinition that diagonalizes the higgsed system.
