In the variant Constrained Level Planarity (CLP), each level $y$ is equipped with a partial order $\\prec_y$ on its vertices and in the desired drawing the left-to-right order of vertices on level $y$ has to be a linear extension of $\\prec_y$. Ordered Level Planarity (OLP) corresponds to the special case of CLP where the given partial orders $\\prec_y$ are total orders.
