When starting off with Team Forms the huge selection of components can be confusing and overwhelming. One particular example of this is when to use a check box vs a select box vs a radio box since they all look very similar.
The checkbox is the simplest of the three and will give you a single check box to capture a yes/no type responses.
The select boxes is similar to a check box however it will allow you to add multiple check boxes in one question. Allowing the user to select multiple options.
The Radio is similar to the select box in that it allows you to add multiple check boxes for a single question, however unlike the select box it will only allow the user to select one of the options at a time.
