Is your feature request related to a problem? Please describe.
I got problem with select dropdown list when it is insde a modal with overflow hidden then then dropdown list has position absolute, but i find that if i move select to the datagrid then the dropdown list has specials atributes with position fixed. Select.js (169 line & 1155 line).

Describe the solution you'd like
It will be very nice if i can manipulate if i want position fixed / absolute in component edit modal. Something like "Allow fixed position of dropdown list"

You might be able to accomplish this with a custom component. Also we are always willing to review any contributions for added behavior, but this in particular isn't something we expect to resource at the time.
