The MultiChoice widget allows selecting multiple values from a list of options. It falls into the broad category of multi-value, option-selection widgets that provide a compatible API and include the MultiSelect, CrossSelector, CheckBoxGroup and CheckButtonGroup widgets. The MultiChoice widget provides a much more compact UI than MultiSelect.
