OR-operator for category

I don't think that is possible with this extension.

Helder is correct, such a feature is not implemented in the Wikimedia version of this extension.

Thank you for your answers. It is a pity. I use DLP for the frontpage of an business-wiki and want to show the last 5 entries of 3 categories.

Well if you're not overly concerned about order you could do something like:

<DynamicPageList>
category = Category1
</DynamicPageList>
<DynamicPageList>
category = Category2
</DynamicPageList>

and it will look like one list (you can even use limit and offset parameters to make the lists interleved). Very far from an ideal solution though.

And if you are interested in alphabetical order, you could use JavaScript to sort the resulting list.

That's the way, I use it now:)
