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).
