Unpoly allows you to stack multiple pages on top of each other. Each stack element is called a layer.
The kind of layer (e.g. a modal dialog vs. a popup box) is called mode.
The initial page is called the root layer. An overlay is any layer that is not the root layer.
||The initial page||no|
||A modal dialog box||yes|
||A drawer sliding in from the side||yes|
||A popup menu anchored to a link||yes|
||An overlay covering the entire screen||yes|
You may configure default attributes for each layer mode in
