Hi,

I have a drop down with 4 options (a, b, c, d). Upon selection of option b, I show certain fields and hide these fields when rest 3 options are selected. 

I followed https://levelup.gitconnected.com/aem-conditionally-show-or-hide-fields-in-touchui-dialogs-with-coral.... for the implementation and its working fine.

Problem: I need to make these conditional items mandatory only when they are visible (i.e, option b is selected). Adding the flag 

required="{Boolean}true" is not solving the purpose as AEM expect it to be filled up even when it is hidden.
