I have found commercial gear that has a toroid holder, a plastic like thing the toroid sits in, the wires pass through and wrap around the form, then get soldered. The form has small pins that fit in holes in the circuit board, and the toroid is held slightly above board.
I have one I got out of something, marked: pe-53933s us patent 5309130 0030-f China I don't think I ever have seen bare toroids glued to a board. There are all sorts of inductor types in pre made forms of all types, none of which anyone could wind at home, for a kit....
