In the context of the so called the Chern--Simons--Antoniadis--Savvidy
(ChSAS) forms, we use the methods for FDA decomposition in 1-forms to construct
a four-dimensional ChSAS supergravity action for the Maxwell superalgebra. On
the another hand, we use the Extended Cartan Homotopy Formula to find a method
that allows the separation of the ChSAS action into bulk and boundary
contributions and permits the splitting of the bulk Lagrangian into pieces that
reflect the particular subspace structure of the gauge algebra.Comment: 14 page
