i's not a bug, it's just a way to force users to specify their model DropdownSearch<MyModel> or DropdownSearch<MyModel>.multiSelection if they uses custom models

compareFn is important (required) in case you are used custom model (not primitive type) it defines how compare two object of type your model.

Excelent! I solved it with: compareFn: (item1, item2) => item1.id == item2.id Sorry for the inconvenience, I didn't know that the compareFn statement was required. Thank you so much
