[Mediawiki-l] DPL usage: Squelch some headingmode headings?

[Ted Osborne]

I am using <code>headingmode</code> with <code>ordermethod=category,title</code> to generate a categorized list of articles:

<dpl>
category=Database programming cookbook recipes
ordermethod=category,title
headingmode=H3
columns=3
</dpl>

But I want to omit some category sections (like "Database programming cookbook recipes", or utility categories like "Pages with custom CSS") from appearing in my list. I.e. I want to select ''all'' "Database programming cookbook recipes" articles, but I want to show only ''some'' of the category headings, and hide others. Any thoughts on how to do this?
