I there any OOTB functionality for the dialog show/hide(toggle) behavior for Coral 3 dialog,
After usage of dialog converter for AEM 6.4 the below blog related component show/hide (toggle) behavior for the Touch UI dialog got broken.
This is broken because you might be using coral3 instead coral2 resources. In Coarl3 class and data attribute values are created differently as shown in vipins5188 reply. You need to update node with granite:class and granite:data nodes to make it work with Coral3
