Select2 has the following configuration options available. Note that this page is a work in progress. The previous release's documentation should cover the gaps here for the time being.

Option Type Description
adaptContainerCssClass
adaptDropdownCssClass
ajax
allowClear boolean

When set to true, causes a clear button to appear on the select box when a value is selected. Clicking the clear button will clear the selected value, effectively resetting the select box back to its placeholder value.
