 Args are useful when writing stories for composite components that are assembled from other components. Composite components often pass their arguments unchanged to their child components, and similarly their stories can be compositions of their child components stories. With args, you can directly compose the arguments:

 Some components require a “harness” to render in a useful way. For instance if a component runs right up to its edges, you might want to space it inside Storybook. Use a decorator to add spacing for all stories of the component.

 That’s not all! Each of the args from the story function are live editable using Storybook’s [controls](../essentials/controls) panel. This means your team can dynamically change components in Storybook to stress test and find edge cases.

 Addons can enhance args. For instance, [Actions](../essentials/actions) auto detects which args are callbacks and appends a logging function to them. That way interactions (like clicks) get logged in the actions panel.

 This parameter would instruct the backgrounds addon to reconfigure itself whenever a Button story is selected. Most addons are configured via a parameter-based API and can be influenced at a [global](./parameters#global-parameters), [component](./parameters#component-parameters) and [story](./parameters#story-parameters) level.

 To sort your stories alphabetically, set `method` to `'alphabetical'` and optionally set the `locales` string. To sort your stories using a custom list, use the `order` array; stories that don't match an item in the `order` list will appear after the items in the list.
