jQuery MultiSelect Plugin was intended to re-factor Cory LaViska’s MultiSelect implementation, but it quickly turned into a complete re-write with a focus on speed and ThemeRoller support. This plugin turns an ordinary HTML select control into an elegant drop down list of checkboxes.
jQuery MultiSelect Plugin is compatible with jQuery 1.4.0+ and all themes from jQuery UI 1.7+. It is known to work in Firefox 2+, IE 6+, Chrome Beta/4, Safari 4 and Opera 10.
