[pmwiki-users] More than one Category Group

[Bellave Jayaram]

Patrick,
	Thanks much. I got the impression that there is something special
about the Category group because of the $CategoryGroup variable.

	I continue to be amazed at how adaptable Pmwiki is and yet how
simple its design and syntax are compared to many others I have seen. Thank
you for continually improving it.

There's really nothing very special about the Category group 
itself, other than that we've created a [[!...]] markup that makes it
easy to create category links.

Any PmWiki page can serve as a "category".  For example, you
could create Films.StevenSpielberg and Films.PeterJackson, and
on each of those pages create a link to Films.DirectedBy, as in:

    Categories:  [[Films.DirectedBy]]

Then, on the Films.DirectedBy page (or anywhere else), you just do

    (:pagelist link=Films.DirectedBy list=normal:)

and you'll get a list of all of the pages that are in the
Films.DirectedBy category (i.e., have a link to the Films.DirectedBy
page), which would include the Films.StevenSpielberg and 
Films.PeterJackson pages.

Same steps apply for Films.OscarWinning -- just put links
to "Films.OscarWinning" in the relevant pages, and then use
pagelist to get a list of them.

Sure, in the same way that searches can be confined to any PmWiki
group.

    (:pagelist group=Category:)         search only the Category group
    (:pagelist group=Films:)            search only the Films group
    (:pagelist link=Films.DirectedBy:)  search only the pages in the
                                          Films.DirectedBy category

The above also works with (:searchresults ...:) instead of (:pagelist ...:).
Or, if you're looking for a searchbox that limits searches to the group:

    (:searchbox group=Category:)        search pages only in Category
    (:searchbox group=Films:)           search only in Films
