Handling radio button inputs is crucial for creating single-selection forms, preference settings, and option choosers in Vue applications. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented radio button controls in hundreds of Vue components over 25 years of development. From my expertise, the most reliable approach is using the v-model directive with the same model property across all radio buttons in a group. This ensures only one option can be selected at a time while maintaining reactive data binding.
