combobox portal vs select portal

[andredewaard]

Right now the combobox portal behave differently from the select portal, this is also clear because the comboboxContent position prop expects different values.
Can we have an option to let them behave the same?
I can understand that you always want to see the combobox input but i moved it inside the combobox content component already so it basically is just a select with an filter option and the ability to select multiple.

How can i achieve this? Select also sets the width the same for the dropdown where the combobox doesn't.
