List of components

Components are JSON objects that you can use when creating an interface in the template builder. For example, use them to add an image, button, or action.

The name of the component is specified in the type property in the format: <category>.<name>. Each component has its own set of acceptable properties described in detail on the component's page.


  • data: Components used for working with data: input, output, or intermediate.
  • layout: Options for positioning elements in the interface, such as in columns or side-by-side. If you have more than one element in the interface, these components will help you arrange them the way you want.
  • view: Elements displayed in the interface, such as text, list, audio player, or image.
  • field: Fields for entering data, such as a text field or drop-down list.
  • condition: Check an expression against a condition. For example, you can check that a text field is filled in.
  • helper: Perform various operations, such as if-then-else or switch-case.
  • plugin: Plugins that provide expanded functionality. For example, you can use plugin.hotkeys to set up shortcuts.
  • action: Perform various actions, such as showing notifications.

Note: Some components are context-specific. For example, you can only use plugins in the root plugins element. You can see the available components in the editor tooltips when you press the Tab key.
