Features

Apply the plugin on a select element and set dependency to one or more other input / select elements (including dependency nesting).
Automatically convert select inputs with class depdrop to dependent dropdowns. The plugin supports HTML5 data attributes to configure the dependent dropdown options.
Automatically initialize dependent dropdowns based on preselected values (useful for update scenario).
Supports both select input with basic options and select with optgroups.
Automatically lock/disable the dependent dropdown until dependent results are available.
The plugin uses ajax call to the server to render the list of dependent options.
Allows a loading indicator to be displayed in dependent select until the results are fetched from the server.
Configure your own loading progress text to be displayed for each dependent dropdown before the results are fetched from the server.
Display a placeholder label with an empty value. For optgroups automatically disable this option.
Triggers JQuery events for advanced development. Events currently available are depdrop.init, depdrop.change, depdrop.beforeChange,depdrop.afterChange, and depdrop.error.
Size of the entire plugin is less than 4KB (about 3KB for the minified JS and 1KB for the minified CSS).
Ability to configure HTML attributes of each option element via ajax response (for example dynamically disabling some dropdown options or adding styles).
