When should I use radio buttons, versus check boxes, versus a scrolling list?
Use radio buttons when we don’t want the user to select more than one item on the list. For instance, we don’t want a user to select more than one VERSION of the age grouping, so we use radio buttons to limit them to one selection only (4 age groups OR 11 age groups, but not both). Use check boxes if it is okay for them to select more than one. This is frequently the case in end node filter variable selections. In such cases, the user may select multiple counties, age groups, or years. However, if the end node selections number more than 12, we’ll want to use a scroll box.
