We have a requirement where the assets metadata associated with the asset should be displayed based on rule.
For example if there are 3 dropdowns. On choosing the value in dropdown 1, the values in the dropdown 2 should be displayed and similarly on choosing the value in second dropdown the value in the third dropdown should appear.
Thanks in advance.
You can populate your subsequent drop down either by writing listeners (if your business rule is not so complex - events like beforeloadcontent etc... from http://dev.day.com/docs/en/cq/current/widgets-api/index.html?class=CQ.form.Selection) else use the servlet to generate the drop down list dynamically.
Please user my earlier post in forum, i hope it will help you to resolve your issue.
if above doesn't help then let me know.
