# setPinned(_:for:completionHandler:)

Called to set the pinned state of the tab.

```
optional func setPinned(_ pinned: Bool, for context: WKWebExtensionContext, completionHandler: @escaping ((any Error)?) -> Void)
```

## Parameters

`pinned`

A boolean value indicating whether to pin the tab.

`context`

The context in which the web extension is running.

`completionHandler`

A block that must be called upon completion. It takes a single error argument, which should be provided if any errors occurred.

## Discussion

This is equivalent to the user selecting to pin or unpin the tab through a menu item. When a tab is pinned, it should be moved to the front of the tab bar and usually reduced in size. When a tab is unpinned, it should be restored to a normal size and position in the tab bar. No action is performed if not implemented.
