jQuery Foggle is a plugin that lets you interact with various form elements based on user-input. It lets you choose which elements to enable (or disable) while the user fills out the form.
- Checkbox issue fixed.
- Works with select elements
Please note that it’s a jQuery plugin and it adds functionality only on the form elements. The demo app is for showing how it works. It doesn’t handle any server side interactions (although, it can be customised to handle them).
