Drop down lists hide a list of options, arranged vertically. You select the downward arrow which then reveals the complete list of options.
- Use a drop down list when you may only select one option from a list of 7 or more options. Use radio buttons when 7 or less options are available to choose from.
- Since all the options but one is hidden in a list, the visibility is low. It is recommended to use radio buttons whenever possible.
- Make the drop down list optional, otherwise specify with a ’Required’ caption.
To show the label drops down, use blue text and Chevron blue. When hovering over the label with the mouse, the label turns Chevron Black (#333333).
See Typography for more accessibility standards.
Size and positioning
Drop down lists are responsive and range in width from 272 pixels on small screens up to 550 pixels on desktop.
- The first drop down list option needs a label and precedes a downward arrow selection to open the list.
- The first visible option is the most common or default option of the set. Do not use the first option as a descriptor or label of the list.
- Each option should be a brief word, description, or name.
- Limit character count to 30 characters with spaces per option.
