Many thanks again Mr. @Calendee
I’m Very sorry for this inconvenience
when I applied your way, I was able to disable drag content on all page within ion-nav-bar
and then I tried to give ion-nav-bar a specific controller and apply
$scope.$root.canDrag = true;
on it, but it doesn’t work.
still can’t drag content from ion-nav-bar only…
What is the reason ?? Can I apply drag content on ion-nav-bar and disable it on the rest of my page ??
