[`IPositionable`](/reference/blockly.ipositionable).
Examples are the trashcan and the backpack in the [backpack
plugin](https://www.npmjs.com/package/@blockly/workspace-backpack).
Positionables are not yet integrated into the focus system.
Built-in positionables are integrated with the focus system, but if you create
your own you should ensure that they work well with it. The built-in ones follow
this pattern:

* Implement `IFocusableNode`
* Ensure that the focusable DOM element (the one returned from
`getFocusableElement()`) has `tabindex="0"`

Depending on the purpose of your positionable, you should also consider
registering a keyboard shortcut to perform its action (e.g. zoom in) or to
directly focus it (e.g. a workspace search field).
