Select2 provides the SingleSelection and MultipleSelection adapters as default implementations of the SelectionAdapter for single- and multi-select controls, respectively. Both SingleSelection and MultipleSelection extend the base BaseSelection adapter.
The selection adapter can be overridden by assigning a custom adapter to the selectionAdapter configuration option.
