# I need to specify that one of the two fields is required, which I’m trying with:

# … anyOf: [{ required: [“email”] }, { required: [“username”] }] …

But this renders two empty tabs. What am I doing wrong?

Thank you.

Hi @sunjith, my guess is that the `anyOf` renderer tester sees this `anyOf` and then takes over. However the `anyOf` renderer expects full schemas within the `anyOf`, so it should not apply here where it’s only used for validation.

You can workaround the problem by providing an explicit UI Schema in which you list all controls. Then the `anyOf` renderer will not apply. Alternatively you could add a custom AnyOf renderer which recognizes this situtation and then behaves like you expect, e.g. by generating a default UI Schema for your object and rendering it.
