How to create a secondary tab

I’ve created a tab page following the site:http://ionicframework.com/docs/angularjs/controllers/view-state/
Now i wanna make a tab in a secondary level, but it doesn’t work in the same way.How can i work it out

Can you explain that in a little more detail? I’m not grokking “wanna make a tab in a secondary level”. Can you sketch out the layout and upload a photo?

something like this sorry that i can’t explain it very well. Now i can tab between home view and about view, but in home view, i can’t tab between sec-tab-a and sec-tab-b.would u mind telling me how 2 work it out? Thx a lot !

Hm… I tried dabbling with it and couldn’t even get as far as you did.

The “Contacts” tab should contain nested tabs but they don’t work well either. Can you share you code?

I just give up the ion-tabs and use

but the layout is quiet a big problem now…

I think you got it pretty well there. I modified the padding a bit. Layout looks better. What do you think?
