Forces: factors that affect selection

• There may be too little room for several radio buttons or even for a checkbox

Common mistakes

Dropdown lists are used in Moodle (1.9) too much, and should be replaced with a checkbox when the choice is just yes/no, or otherwise usually with radio buttons.

A dropdown menu is not a navigation menu, but a form element. Hiding the submit button and making the form element submit automatically when a value is selected raises serious accessibility issues: among others, keyboard navigation is seriously hindered on many browsers. Where one is needed, a navigation menu (usually a CSS styled unordered list in HTML) should be used.

Checkboxes and Radio buttons should be used instead in most cases.
