Expandable Column component

The Expandable Column UI component is an extension for Column. It alphabetically sorts the options associated with a record/row and renders several options (the number is defined in configuration) into a cell. The full list of options is displayed in a tooltip implemented by the Tooltip UI component <Magento_Ui_module_dir>/view/base/web/js/lib/knockout/bindings/tooltip.js.

The Expandable Column component can be used in Admin and the storefront.
