Other than a question I had about using a talon instead, the code looks fine. Nice work buddy.

[revanth0212]

Would it merit if we create and send it over from the talon instead? By doing so we are opening up the component to have custom definitions for shouldRenderVisibilityToggle. In the default case, it will be wishlists.length > 1. What do you think?

[sirugh]

Sure, sounds good.

There are some test failures. Check it out dude.
