startAt active item: how to do it?

[ezersky]

Greetings!

I'm trying to use it for navigation. How to make an activated item centered on page load. Not at the beginning or the end, but in the middle.

I've tried both basic and centered, but they all have a startAt parameter with a value of 0-4. There is any possibility to use in startAt something like .active?

Task: when loading the page, show active item in the center of the frame
