AEM6.4 SP3 Asset metadata editor | dynamically populate list upon selection change

[#1]

Hi All,

I have a requirement to populate the 2nd list when changing the value in first list in asset metadata editor

Say for example Option1, Option2 are the dropdown in  first list.

When selected option1, 2nd list should have values (xxx,yyy,zzz)

When selected option2, 2nd list should have values (aaa,bbb,ccc)

Please let me know if someone has any idea on this. Any help  is highly appreciated.

Thanks,

Pradeep

This is  neither page properties nor component dialog. I clearly mentioned asset metadata editor. In asset metadata editor there is a drop-down. In first drop-down I have fixed values, in 2nd drop-down values are dynamic those are based on selection changed in first drop-down.

I hope you understood my question and problem.

Thanks,

Pradeep
