A multi level dependent dropdown JQuery plugin that allows nested dependencies. The plugin allows you to convert normal select inputs, whose options are derived based on value selected in another input/or a group of inputs. It works both with normal select options and select with optgroups as well.

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.
• 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.
