Onepage_XH offers tools to design and administrate so-called "onepage" websites. In the backend you can administrate the site as usual, but in the frontend a special template is used, which displays all visible pages at once, and the menu links to automatically inserted anchors on the same page.
It requires CMSimple_XH ≥ 1.6.3 and PHP ≥ 5.2.0. It is released under GPLv3.
Onepage_XH couldn't be tested so far in various environments. It is a so called alpha version. Use with utmost caution!
