questions on granite UI dialog fields

[Naidu_Jakkana]

1) do we have any pathbrowser to have drag and drop functionality from asset finder like we do for pathfield in classicUI ?

2) is any information on customizing multifield to composite fields ?

3) is there any info on validations for granite dialog fields ?    like we have listeners in classic UI and minLength  etc ??

I have been trying to get this information but could not able to get it so far.   Much apperciated if any help provided.

I just found that http://help-forums.adobe.com/content/adobeforums/en/experience-manager-forum/adobe-experience-manage... for drag and drop will not work for pathbrowser.
