Get to know Composer, where you create and edit custom overlays
Singular’s overlay builder, Composer, is where you create and edit custom HTML5 overlays. On this page, you'll find an overview of the layout of Composer and and a list of Composer shortcut hotkeys.
Composer contains four main areas:
- 1.Composition tree
- 2.Property panel
- 3.Output window
- 4.Data interface and control panel
Main areas of Composer
This panel shows the organizational structure of the elements in a composition or sub-composition.
Here, various editors are available to modify and change the parameters of a selected widget, group, or sub-composition.
In this panel, you can preview overlays.
This panel allows you to define links to external data and specify widget properties you want to expose to external control applications or the Singular APIs.
A closer look at Composer
1.1 Composition breadcrumb
Here you can see the size and name of the composition you are working on.
1.2 Composition tree toolbar
This toolbar allows you to add, copy, and paste elements, such as widgets, groups, and sub-compositions, into a composition. It also contains a search bar, undo/redo buttons, open/close all groups buttons, and the composition navigator button.
1.3 Composition navigator
This floating user interface is for navigating between sub-compositions within a composition. Here you can trigger in and out timeline animations, assign a sub-composition to a logic layer, and adjust transition timers. Access it by selecting the composition navigator button in the composition tree toolbar or by using the shortcut command + F (Mac) or control + F (PC).
2.1 Composition script editor
Above the property panel is a button to open the composition script editor and another to open the composition script editor in safe mode.
3.1 Preview toolbar
In this toolbar within the output window, you can turn on/off bounding boxes, choose the aspect ratio of the device or the composition you want to build for, take a thumbnail snap of the frame, or open a new tab to see the output of your work on a clean page.

These buttons trigger In and Out animations.
