Rails

I’m newbie for ROR.

I was create select box for employee who swap position when they work.

ex. mr.John has default position as a service but he can swap position
to driver .

In select box i want to show default position first.

but my app it not show default first it must select by myself.

how i create the select box by selected value with ROR command

now i use

<%= options_from_collection_for_select @areas, :id, :name, (shift.area_id if shift) %>

No! Use intelligence! the entire select tag is replaced by collection
select. Look on the API for syntax.
