Perspective Split Container

Is there a relatively easy way to create a split container in Perspective? This really doesn’t have to be mobile friendly.

Would you mind defining what you mean by split container? What’s your use case?

Like WinForms control, the case is to split the container via mouse (dragging).

Resurrecting this question, is there a way to do this in Perspective, example in GIF and what the tag browse has?
