Dropdowns present a list of options that can be used to filter or sort existing content.


Dropdowns (also known as a dropdown menu, drop menu, pull-down list, picklist) is a graphical control element, similar to a list box, that allows the user to choose one value from a list. When activated, it displays (drops down) a list of values, from which the user may select one. They can be used in menus and tabs.


Use when

  • Filtering or sorting content on a page.
  • Single selection from a list is necessary.

Don’t use when

  • Providing only two options. Instead, use a Radio Group or a Switch.


  • Dropdowns can be activated by clicking a button, an icon, or a header. See Inputs for dropdowns in form input fields.
  • Dropdown functionality is indicated by a small trailing arrow or an ellipsis (not applicable to icon dropdowns).
  • Within a dropdown, you can separate groups of related menu items with a divider.


  • Make sure the items in the list are in logical order (alphabetical, chronological, order of importance, etc.)
  • If no item is preselected, use something like “Select a vendor” or “Select an account” in ghost or hint text format. If you can’t gray out the text, you can use some kind of indicator, like parentheses.
  • If you need to, you can display ”None” as one of the options. It should have the same text formatting as the other options in the list.
  • Dropdowns are activated by clicking, not hovering.


  • Present drop-down selections in sentence case (“Select an account”). If the drop-down list contains formal names, such as customer names or accounts, then those selections will appear in title case.
  • Don’t use “deselect.” Instead, use “clear.” The term “deselect” causes a problem for localization.
  • The list of options should be sorted in a consistent order (alphabetical, chronological, the most selected option, or by order of importance).
  • Don’t end text in a select with a period.
  • Keep option names as brief as possible. Aim for under 5 words.
