Custom DropDownChoice using HeaderItem

[prasopes]

Hi,
I'd like to have a DropDownChoice that gets transformed with Javascript on
each rendering. The Javascript manipulates the option tags. Is it possible
to achieve this using override of renderHead method?
I tried:

But when the Javascript gets called, the select has no options yet. Am I
headed in a completely wrong direction?

DropDownChoice - single choice, preselect automatically

[prasopes]

I know I can preselect the value of DropDownChoice by setting the
corresponding value in the model.

My use case is this: I have several DropDownChoice with
OnChangeAjaxBehaviors. Selection of value in one DDChoice enables second
DDChoice. The values in second DDChoice depend on the value selected in the
first DDChoice. In case the second DDChoice has only one possible value, I
would like to have it preselected automatically.

However, I'm unsure in which lifecycle phase I should look at the number of
options of second DDChoice and manipulate its model to achieve preselection.
