I am creating a web page using mendix, where i am trying to create multiple options selectable in my dataview using checkbox widget. For example i am searching a book in the genre of crime-drama, romance-thriller, like that. I have enumeration like romance, crime, thriller, drama, sci-fi. When I use radio buttons or drop down widget i can select only any one of these. I want to select at least 2 items in the checkbox. So please someone suggest to me how to achieve this in a much simple way.
