Dropdown Check List is a JavaScript Plugin for jQuery library that transforms a regular select html element into a dropdown checkbox list. The Dropdown Check List jQuery widget transforms a regular into a dropdown checkbox list.
Usage
Dropdown Check List plugin dynamically builds a container with checkboxes and labels to replace the select element. You can customize the look and feel of your dropdown check list by simply updating CSS file.
$("#select_id").dropdownchecklist();
The existing select element with id=’select_id’ is replaced by a dropdown checkbox list widget. See the Demo Page for a detailed description and live examples.
How does it work?
Dropdown Check List uses the existing structure of the html select elements on which it is applied to dynamically build a container with checkboxes and labels then hides the original select element. The plugin does not change in any way the existing select element, only syncronize the checked values from the new container to the original select. This approach has the added benefit to allow the use of the plugin with any server technology.
