Hi @kaikubad ,Can you explain a bit more, as Styles in RTE is not OOTB, and also we don't have options to add through component styles plugin policy.Here is what i have in my text policy.:Where you want me to add ?

When I select Styles from RTE system it is getting combined. I want that only one styles in RTE should get selected at a time.When i select One, other should get unselected.
