If you are looking for tidy solutions, I'd suggest trying the decode
modifier that is part of Petal::Utils v0.06. This would make your code
look something like the following (untested!):

 <option
     tal:repeat="cat cat_list"
     tal:attributes="selected decode:$cat/id $item/cat/id 'true'"
     value="$cat/id"
     petal:content="cat/name">Category</option>

Unfortunately not. It's come up a couple times on the list. In the
meantime, I suggest browsing the mailing list archives. Besides some
interesting conversations (some of them a bit esoteric), you should find
some code samples. I have a test file that contains many examples which
I can send if you don't find it in the archives. Let me know.


Cheers,
William
