scenario, from a drop-down list options 1, 2, 3, if you check option 1 the seller is A, if he marks option 2, the seller is B, and he continues but the user does not know who is seller A, B, C,
the idea is that it does not select from another drop-down list, that is assigned automatically question, from a drop-down list it is possible to assign the value of a field,
using sharepoint with a label it's easy, with a rule I change the property "TEXT" but connected to sharepoint I can not find a solution
