This question is in the spirit of [another older question][1]. We say that a poset $(P,\leq)$ is *Priestley-topologizable* if there is a topology $\tau$ on $P$ such that $(P,\leq,\tau)$ is a [Priestley space][2]. Is it true that a poset $(P,\leq)$ is Priestley-topologizable if and only if all its connected components are Priestley-topologizable?
