[Zope-dev] This may be simpler...

Okay fair enough...

Why bother? there's a builtin method to do this for you!

Maybe try this instead (assuming getContext returns a list of actual
objects):

    <dtml-in getContext>
       <option value="<dtml-var absolute_url>/manage_container"
       <dtml-if expr="currId==getId()">
        SELECTED
       </dtml-if>
       >
       . . .
       </option>
    </dtml-in>

I don't know where currId comes from so I'm not sure it does what it is
supposed to do...

Now why on earth would it do that? (It won't by the way, unless you code
it like that, and even then it would work in the way you've assumed)

This is very confused...

Well yeah, the dtml-in means that stuff inside it gets executed for each
object in the list.

Hope this helps,
