In the "New Connection (vlan)" dialog, the "Parent interface:" drop-down selector offers a list of the system's eligible interfaces. Current behaviour: list of interfaces selectable as parent interface contains only Wired Ethernet and "lo" interfaces, although a Bond interface exist. Desired behaviour: list of interfaces selectable as parent interface should contains Wired Ethernet, "lo" and Bond interfaces. In Network Manager commands such as 'nmcli con add type vlan ifname bond0.123 con-name bond0.123 id 123 dev bond0' the device argument can take bonded interfaces just as well as individual physical devices. In plasma-nm it should be as well.
