Don't think there's any such attribute. ng-focus takes an expression which evals to true/false. You could back that with a method that returns true when the relevant pane is selected.
Although, top of my head, I'm not sure how you should do that (I'm rapidly trying to forget AngularJs and focussing on Angular 2)

I think my problem is that I'm using nav-tabs. I found related discussion but it's a bit over my head

Those are JQuery solutions (which should work)


>BTW, can you please also help with my other thread? When I left to sleep last night (I worked till 12 am) I realized my solution is not going to work in the case my message returns nothing and I do want the Save to fire. Right now it sort of works because I was testing with returning my error message.

What do you mean by 'message returns nothing' ?
