<dtml-in filter_row prefix="sq">
<dtml-var expr="sq_item['filter_id']"><br>
<dtml-var expr="sq_item['bez_ref']"><br>
<dtml-var expr="sq_item['col_span']"><br>

or
<dtml-in filter_row>
<dtml-with seq-item>
<dtml-var filter_id><br>
<dtml-var bez_ref><br>
<dtml-var col_span><br>
<hr>
</dtml-with>
</dtml-in>
(sorry, they're untested -- you may have to fix)
The point is, you will loop through the *sequence* of *dictionaries*. Then
you act on each dictionary -- referencing its elements. You can use python
syntax to retrieve dictionary elements from the seq-item (prefix is a DTML
kludge to make the syntax more python compatible), or "dtml-with" to make
the dictionary the current namespace. There are probably other ways to do
it as well.
Cheers,
Terry
