Combobox

​

When to use

• More than ~12 options, where typing to filter is faster than scrolling.
• The user knows roughly what they’re looking for (e.g. selecting a country, an asset name, a tag).
• Forms where users need to search and select from a predefined list.
• When users need to add new options that don’t exist in the list yet.

​

When to use something else

• Fewer than ~12 options: use Select, Radio, or Checkbox depending on context.
• The user is unfamiliar with the available options and wouldn’t know what to type: a visible list is less intimidating.
• Very large datasets where filtering may cause lag: consider a Data grid with toolbar filtering instead.
• Free text input with no list to select from: use Input or Textarea.

​

Dos and don’ts

• Do group related options if the list spans multiple categories.
• Don’t use it for simple yes/no or small option sets: the search affordance implies more options than are there.

​

Behavior

• Single-select: the menu closes immediately on selection.
• Multi-select: the menu stays open until the user clicks outside, presses Escape, or presses Enter.
