Lack of ability to hide non eligible components when using the Editable flag

[NoFriendsInProgramming]

Basically for designers, where with the current system you can still select Parent components when using the Child attribute and vice versa. When there are a lot of eligible components it´s hard for a designer not intimate with the code to know which component fits the attribute. Yes, an error message shows up, but you don´t know which components of the list are child components. And yes, you could just manually drag and drop but it ends up going against the purpose of the Attribute.

Hopefully not nitpicky or anything, this is great, but this tiny QoL improvement would really help.
