Multi level tabbar problem

[anyongnan]

Hi,
I am new to Onsen. I am trying to make a segment like tabbar which also have their own tabs like: https://codepen.io/ouz-y-ksel/pen/PgdOBp
The problem is changing inner tabs cause parent tabs to change.
I have searched old questions and found only this which is not exactly but is mentioned in the comments: https://stackoverflow.com/questions/35123385/onsen-2-0-adding-event-listener-to-ons-switch-with-javascript

Thanks in advance.
