ckgedit works with two of the main navigation plugins,
simplenavi and
indexmenu.
For examples:
indexmenu:
http://www.mturner.org/xen_server/
simplenavi:
http://www.mturner.org/devel/
It also works with the
navi plugin. If you are using one of these and are having problems there is probably a conflict with another plugin. However, if you are using the navi plugin or any other navigation plugin that requires a list, it's probably best to create your menu listing in the native dokuwiki editor, not in ckgedit.
