Hi all, I'm working on a news product and now i want to make a chain menu, which shows the brothers and sisters of the object. I have made a python method for this. I get back a list of three tuples : [{sortkey,object1},{sortkey,object2},{sortkey,object3}] The first listitem is the previous object, the second the current and the last the next object. The first item is None if there is no previous object. How can i implement this in DTML? I've made a start but it doesn't work properly(the python method is called list_chain): <dtml-in list_chain> <dtml-if "_['sequence-item'] != None and _['sequence-number']==1"> <a href="<dtml-var "_['sequence-item'].absolute_url()">">Previous</a> <dtml-elif "_['sequence-item'] != None and _['sequence-number']==2"> <dtml-var "_['sequence-item'].title_or_id()"> <dtml-elif "_['sequence-item'] != None and _['sequence-number']==3"> <a href="<dtml-var "_['sequence-item'].absolute_url()">">Next</a> </dtml-if> </dtml-in> Can anybody help me? Greetz and thanks, Nico
