Add widgets to tab

I use tabview and experiment enjecting views and widgets into tabs.

If insert into first tab all work nice, but if I try add widgets into second tab this work bad.
I try some methods with target parent into webix.ui, and use container propeties in “markup”

I found solution - add nested level.

But there was one problem: when you switch tabs list height ceases to be 100%

To keep the height constant, use the fitBiggest option for the multiview: http://webix.com/snippet/583a4c02

Thanks! Already use it.
