# Stack

The stack container is a container widget, which puts its child widgets on top of each other and only the topmost widget is visible.

## Features

- Two size hint modes.
  - `dynamic:true`: The stack's size is the preferred size of the visible widget
  - `dynamic:false`: The stack's size height is the to the height of the tallest widget and the stack's width is set to the width of the widest widget

## Description

The stack is used if exactly one out of a collection of many widgets should be visible. This is used e.g. in the tab view widget. Which widget is visible can be controlled by using the `selected` property.
