Hi Team,

In AEM 6.1 we are creating the metadata schema and in that schema we want to add two drop downbox and based on the value selected in first dropdown box, the second dropdown box should be populated with values?

Is it possible at metadata schema form OTB? If not the OTB then how we can implement it via script? Can you please suggest?

Thanks
