Hello,
thanks a lot for this great theme and this fantastic support.

Using the atahualpa 3.7.3...
- I´d like to include categories and pages in one menu bar. What ist the most elegant way?
- How do I also include child pages / categories?
- And how do I sort them?

Sorry, but I can´t find the answer in the forum. Is there already a solution? Thanks again!

Just use the WordPress menu under Appearance>Menus. Using that you could even have a page as a child of itself.

Thanks lmilesw for the quick answer.
It´s always the same. First you´re searching long time for an answer. After posting the question you got the final inspiration.
It´s so simpel.
1. First define the menu1 in WP-menu Options.
2. Then put it where ever you want in ATO>Stlye Header Area by using %pages for menu1

:-)
