Thanks to folks who responded to my question (as in Subject), especially Jonathan and Dylan. I've been trying to DMTL my way through this, on and off, for several weeks. Simply speaking, I have a bunch of files in a directory and I want to (automatically) create URLs that will list groups of files by title so that all files "Category A*" are listed together. I decided to try the way of ZCatalog (hint provided by Jonathan, Small Business Services) first and it proved to work "as seen on the Web". Here are the steps I've done to get it working - it's easy, but I couldn't find any how-to's on this so here's a mini how-to, I hope others will be able to find it in archives when needed. 1. ZCatalog The relevant doc for v2.6 are here http://zope.org/Documentation/Books/ZopeBook/2_6Edition/SearchingZCatalog.st... (I use Zope 2.5.x) So, I found the Web docs very confusing so I just tried intuitively - added ZCatalog, went to its Find Objects tab, catalogued all objects in a directory/folder Then I created a pair of forms (Search/Results) by adding ZSearch Interface. I tried searching for *keyword* in Title, it worked. 2. Search Form To be able to search "*keyword*" (in title, in my case) in an easier way (without having to enter the asterisks), you can simplify the default search form to something like this: <form action="categories.html" method="POST"> <p>Select files of type: <select name="title"> <option value="*Category A*" selected>List Category A</option> <option value="*Category B*" selected>List Category B</option> </select> <p><input type="submit"></p> </form> 3. Results Form If necessary, modify the default search results form to list URLs to files. 4. Further improvements If you want to combine steps 2 & 3 into one page, refer to http://www.devshed.com/Server_Side/Zope/ZopeForm/page6.html Instead of his <dtml-if submit>, I have <dtml-if title>, also for the dtml-else tag. Again, thanks to those who helped.. Cheers Sean
