Our aim in this paper is to introduce and study a new sort of fuzzy sublattice (ideal, filter) of a lattice called (is an element of,is an element of boolean OR q) -fuzzy sublattice (ideal, filter). These fuzzy sublattices (ideals, filters) are characterized by their level sublattices (ideals, filters). Finally, we give a generalization of (is an element of, is an element of boolean OR q) -fuzzy sublattices (ideals, filters).
