  This paper has two goals; the first is to generalize results for the
existence and nonexistence of warped product submanifolds of almost contact
manifolds, accordingly a self-contained reference of such submanifolds is
offered to save efforts of potential research. Most of the results of this
paper are general and decisive enough to generalize both discovered and not
discovered results. Moreover, a discrete example of contact CR-warped product
submanifold in Kenmotsu manifold is constructed. For further research
direction, we addressed a couple of open problems arose from the results of
this paper.
