How to create Interdependent drop down in Wizards

Hi All,

I have created "Country" and "City" attributes, also created respective enumerated value list.

Like,

Country : India, US

City : Mumbai, Pune, New York, Washington DC.

My requirement is, When user select the value for Country Attribute, respective City name should be populated for City attribute drop down.

e.g. if user selected "India" for Country attribute value, for City Attribute "Mumbai" and "Pune" only be populated.. New York and Washington Dc is not visible for user as this cities are not part of India.

Kindly let me know how i can achieve this.

Regards,

Vivek
