In AEM Forms drop down

[pratikshah]

we have 2 drop down when we select value from 1st drop down it will decide the value of 2nd dropdown.

So how to do it ? 
1 way is using clientlibs but there is other way using the aem form rules any idea on that ?

Hi @pratikshah If you are referring to Adaptive forms then there is a rule editor available OOTB in AEM Forms - https://experienceleague.adobe.com/docs/experience-manager-65/content/forms/adaptive-forms-advanced-...

Please note that it's not included as part of AEM Sites and is a separate add-on.

You need to write the code to dynamically populate the second dropdown on the change or exit event of the first dropdown.

eg.:

Need to create the mapping like the first dropdown has the country and the second dropdown has the city for that country.

India > Mumbai, Delhi

Australia > Sydney, Melbourne

You can maintain this mapping in xml data or db.
