Dependent Picklist(Option Set) in CRM 2013

Solution Features

• It provides a generic, re-usable JScript library that can be used for any pair of option set fields.
• It allows for a chain of dependent option set fields. Because each dependent option set field options are filtered based on the value of another field, additional option set fields options can be filtered by the option chosen in the first dependent option set field. This allows for the possibility of a set of hierarchically dependent option set fields.
• The filtering of dependent options is set in an XML Web resource. This allows for changing the option mappings without changing the code. Editing an XML Web resource is easier for a non-developer to configure options with less opportunity to break the code.
• The solution supports multiple languages. The filtering is based solely on the data value of the options rather than any text in the options.
• Filtering works for any number of instances of an attribute control on the form.
