Thanks for raising this question about integrating your online help with Jive. At the moment, this option isn't available out of the box and will likely require some customization to integrate and retain navigational functionalities. If you're developing an integration yourself, I would recommend posting to the Developer space for ideas and guidance from the development community. Otherwise, you might look into an engagement with Jive Professional Services (PS).
I hope this helps. Let me know if you had any other questions or if you'd like to be put in touch with our PS team.
You can publish help and documentation from a myriad of techcomm authoring tools and formats (to include DITA, Madcap Flare, Screensteps, Robohelp etc.) into Jive using the Zoomin for Jive product (http://www.zoominsoftware.com/products/zoomin-jive/ ). I've emailed you in private with additional details.
