can we add additional prop for attach to field like append-to-body

[select-good-way]

Hi, i want to use select box on dialog , but when I am using it with append-to-body property dropdown getting displayed behind the dialog and also I have increased the z-index but it still behind the dialog , I set append-to-body to false i showing dropdown on dialog properly but my dialog having few fields and drop down getting over flow in side dialog container and getting hide dropdown . can you please add the new pro as attach to means if we attach it to dialog with its id attribute and html tag then dropdown should show on top instead of creating overflow to the container.
