  • tasks - Items in this category will be placed into the standard Tasks category. There can be only one such category, and it will always be displayed at the bottom of the Jump List.
  • frequent - Displays a list of files frequently opened by the app, the name of the category and its items are set by Windows.
  • recent - Displays a list of files recently opened by the app, the name of the category and its items are set by Windows. Items may be added to this category indirectly using app.addRecentDocument(path).
  • custom - Displays tasks or file links, name must be set by the app.
• name String (optional) - Must be set if type is custom, otherwise it should be omitted.
• items JumpListItem - Array of JumpListItem objects if type is tasks or custom, otherwise it should be omitted.
