I have a table with a list of items & various columns.
One of the columns is
Type, of which the possible values are A, B, C etc...
The user is able to assign a binary value
NO via a dropdown.
At any one time, only a single item per
Type can have
YES (functionally, its like a radio button)
If the value of item Owl is
NO and the user sets it to
YES, it will remove the existing
YES from item Ape and automatically assign it as
An example of such a table is below. As you can see, only one item in each Type A & B can have the value of
How do I convey to the user that only one item per Type can have the value of
Is X? set to
I did not use radio buttons because the user might think they can only choose one item from the whole table.
Whereas in this case, its possible to choose 2 or more (as long as they are of different Type)
Feel free to suggest a totally new way of doing the UX if you think its clearer.
