You want to integrate a chat button for the built-in chat in main menu/page menu/menu bar of Woltlab community software?
Simply looking on the appended screenshots exactly, think, build, configure, and enjoy the new chat button implementation.
This chat button is naturally integrated also in the "International Chat Gallery".
Cosirex - so good - so what...?
Sorry for the non-translation of teh screens. But it's easy too, because you only have to follow the path written in the images and there you find the same configuration sites in english language.
The rest comes without thinking...
Lots of greets and much success
