module: fortios_wireless_controller_wtp_group
short_description: Configure WTP groups in Fortinet's FortiOS and FortiGate.
description:
    - This module is able to configure a FortiGate or FortiOS (FOS) device by allowing the
      user to set and modify wireless_controller feature and wtp_group category.
      Examples include all parameters and values need to be adjusted to datasources before usage.
      Tested with FOS v6.0.5
version_added: "2.9"
author:
    - Miguel Angel Munoz (@mamunozgonzalez)
