This paper describes unification of the Higgs doublet in the standard model and the Higgs field to break the grand unified theory group to stabilize the sliding singlet mechanism which can solve the doublet-triplet splitting problem. This attractive mechanism has been generalized to apply it to many unified scenarios. This research attempts to build various concrete E₆ unified models by using the generalized sliding singlet mechanism.
