Closed discussion was below.
I want to be selected from the image set of enumerated type. It is not a selection of text.
So the Option Field can not be realized.
When my case as an example ...
+ -Rank (Refer one Rank)
+ -Leader (Refer one Member)
+ -Members (Refer multi Member)
That is the schema.
Also bind the team list, not worn follow up Rank.Icon.
Reluctantly, only to copy the same image by adding a Member.RankIcon.
There is also the other, in my spear want concept, I want to bind to element from reference of 5 hierarchy.
I would like to ask this corresponds to the development team. Please your help.
