The MultipleSelect question is good for gathering information on preferences where there are more than 1 valid responses.
Up to 15 choices, are displayed vertically using radio buttons. You may select none or any number of the choices.
An optional Other box may be added to this question which allows an alternative or additional choice to be entered.
Checking the Randomise Choices field will make the choice options list in a random order each time, with the other option, if selected, always at the bottom.
The MultipleSelect question, when initially presented, does not have any options selected, and if skipped without entering any selection, a null entry is recorded. By checking the Force reply field, the question can not be skipped without at least one of the options being selected.
