Tapestry Combobox

Hello,

Have just started with tapestry and web designing. I try to implement
combobox

<t:select t:id="carstype"/>

where carstype referring to enum.The selected value gets stored in database.
I need a solution where my combobox has the first value as database
value and other
values from ENUM.

Any efficient solution for this?

Thanks!
