I may be going insane, but when you first introduced relations type fields (pivots) there were two options
The multi-select fancy combo box (which is what we get now) which is awesome
but there was another option where all the options were laid out like.. for want or a better term.. radio buttons where you just clicked on what you wanted and they changed colour
We now only seem to have the combo box options.. or maybe I am wrong and this was only for enumerations.
Is this an error, or am I making stuff up
