This is earch box with a filter and a large drop down menu. We will use jQuery in both elements for the effect. We will also use plenty of CSS3 properties to create some slick looking details. Search Box with Filter This search box reveals a drop.
I highly recommend you use this version over the plugin version. It has a more robust feature set, is faster, and is much more flexible. MultiSelect turns an ordinary HTML select control into an elegant drop down list of checkboxes with themeroller support.
