Hi Folks

I'm trying to figure out how to retain form data after a post (in the =
event of an error of some sort) so I fill in the values of the form with =
what was passed. For example, a registration process that must do a DB =
query and return the same form if the username is already taken so the =
user can pick another without filling out the whole thing again.

How would I add the "selected" attribute to an <option> html tag in zpt? =
Does the tal:attribute method work? If so, wouldn't I need to tell it =
what attribute to assign a value to?

Basically I want to do this in pseudocode
while (dropdown)
if dropdown[n] =3D=3D options.dropdown_from_post:
    <option "selected">Blah</option>
else:
    <option>Blah not selected</option>

Thanks

-jim
