Vælgerne her er specifikke for Wufoo-markering, men begreberne på arbejdspladsen kan fungere i enhver form. Den overordnede idé er, at du gør standardradioknapperne og afkrydsningsfelterne usynlige ved at indstille deres opacitet til nul og erstatte dem med grafik. Brug derefter: markeret vælger til at skifte grafik mellem deres markerede og ikke-markerede versioner.
