@PK, your question is a little too open-ended to answer effectively. The ZoneFlex documentation does fully cover the "modes" the AP (with or without a controller) can support and how to configure them, but that's too much information to provide here.
It might be better if you let us know what your use-case is and then we can answer whether our product can support it.
An AP can be connected to another AP in mesh mode.
An AP can operate in bridged mode (where traffic is dumped directly the the appropriate VLAN(s) on the switch it's connected to)
An AP can operate in tunneled mode where all it's traffic gets encrypted and tunneled back to a controller, and then from the controller to the LAN.
