Hi phl, Yes this is fully implemented in xwiki and it's actually one of xwiki's strengths. You have 2 possibilites to implement it depending on whether you want form editing to enter new data or not: * if you do then you should implement something as described in the FAQ tutorial: http://www.xwiki.org/xwiki/bin/view/DevGuide/FAQTutorial * if not, then you can simply tag your pages (see http://www.xwiki.org/xwiki/bin/view/UserGuide/Tags) and the query tags in the page where you want to list them using a HSQL query (see http://www.xwiki.org/xwiki/bin/view/UserGuide/Programming and check the code zone for lots of examples on that).

Hello,

1) I have not yet understand what is a category in xWiki and how to fill it (I succeed to create mine, but I can't put anything into it).

2) In fact, I looking for a category as mediawiki.

For instance, my xwiki is a presentation of books. So when I see the book main page, I will have the text and the list of the subcategories (book of mathematics, book of physics, ...).

When I add a new sub category (like books on computer sciences), I would like that it will be automatically add to the book main page. And I will also that this page shows to the user the subcategory like : documentation about compiler, and documentation about wiki.

And in the page about wiki, I would like to have a list of hyperlink to page that describes mediawiki, xwiki, .....

Are this kind of mechanism fully , partilly coded into xwiki ? If not how to code it ?

Thanks, PHL. -- View this message in context: http://www.nabble.com/Category-%28and- hierarchical-category%29.-tf3704021.html#a10358295 Sent from the XWiki- Dev mailing list archive at Nabble.com.
