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?
