multiResolve() doesn't allow the user to choose a navigation target

According to http://www.jetbrains.org/intellij/sdk/docs/reference_guide/custom_language_support/references_and_resolve.html 

"An extension of the PsiReference interface, which allows a reference to resolve to multiple targets, is the PsiPolyVariantReference interface. The targets to which the reference resolves are returned from the multiResolve() method. The Go to Declaration action for such references allows the user to choose a navigation target."

I implemented multiResolve() but didn't see the options that are returned from the multiResolve() method. Is there any other place that I should take care of? Thanks!
