[Issue]: Bad expandability: Methods that should be protected are private + relation return type too strict

[softwaretechniker]

What happened?

Trying to inherit from SelectTree ends in a mess:
First you can not reuse methods like buildTree() etc. because their scope is private instead of protected.
Second, getRelations return type is strictly bound to BelongsTo/BelongsToMany relation and can not be extended.

Is there a particular reason you need to override the buildTree method? This method contains all the necessary logic to ensure the tree is properly constructed and displayed in the options field.

If you’re looking for more relational support, I’m always open to adding additional features!
