Select

Selects are used to choose one or more items from a list of options.

Demo

Usage

When to use

• Choosing one or several options from a list of many. Use a select if there are many options to choose from, especially in compact layouts.

When not to use

• Ordering selections. Don't use a select to choose options when their order is important. Use a Transfer instead.

Variants

Single select

Demo

<SingleSelectField label="Aggregation type">
    <SingleSelectOption label="One" value="1" />
    <SingleSelectOption label="Two" value="2" />
    <SingleSelectOption label="Three" value="3" />
</SingleSelectField>

• Use a single select if the user can only choose one option.

Multi select

Demo

<MultiSelectField label="Priority" selected={['1']}>
    <MultiSelectOption label="Very low" value="1" />
    <MultiSelectOption label="High" value="4" />
    <MultiSelectOption label="Very high" value="5" />
    <MultiSelectOption label="Critical" value="6" />
</MultiSelectField>

• Use a multi select if the user can choose one or more options.

Format

Label

• Show a label above the select to show what it's for.
• Labels should clearly describe the selection to be made. Don't use long sentences.
• A noun is often the simplest choice of label, rather than a verb. For example, Period type is more concise in a layout than Choose a period type. Only use a verb if the use of the control is ambiguous.

Placeholder

Demo

<SingleSelectField label="Label" placeholder="Choose an option">
    <SingleSelectOption label="Option one" value="1" />
    <SingleSelectOption label="Option two" value="2" />
    <SingleSelectOption label="Option three" value="3" />
</SingleSelectField>

• Only use placeholder text to clarify what kind of content is expected.
• Placeholder text shouldn't repeat the label.
• Always use placeholder text if a label isn't used.
• Placeholder text disappears when choosing an option, so make sure it's not critical.

Help text

Demo

<SingleSelectField
    label="Aggregation type"
    helpText="Choose the aggregation type to apply to imported data."
>
    <SingleSelectOption label="Option one" value="1" />
    <SingleSelectOption label="Option two" value="2" />
    <SingleSelectOption label="Option three" value="3" />
</SingleSelectField>

• Use help text to tell the user about any limitations or expectations for the content.
• Help text can also be used to clarify what the input is for if it's a complex concept.

Size

Demo

<SingleSelectField dense label="Dense sized select">
    <SingleSelectOption label="Option one" value="1" />
    <SingleSelectOption label="Option two" value="2" />
    <SingleSelectOption label="Option three" value="3" />
</SingleSelectField>

• Selects are available in two sizes, regular and dense. Regular sized selects are useful when there's space available. Use dense sized selects in compact, information-dense interfaces.

Width

• A selects width should reflect the expected content.
• Avoid full-width selects, which can be visually unclear.

Options

Filtering

Demo

<SingleSelectField filterable label="Label">
    <SingleSelectOption label="Option one" value="1" />
    <SingleSelectOption label="Option two" value="2" />
    <SingleSelectOption label="Option three" value="3" />
    <SingleSelectOption label="Option nine" value="9" />
    <SingleSelectOption label="Option ten" value="10" />
</SingleSelectField>

• A select can show a filter control that filters the available options.
• Use a filter when there's many options, more than 10, to choose from.

Clearing

Demo

<SingleSelectField clearable label="Label" selected="1">
    <SingleSelectOption label="Option one" value="1" />
    <SingleSelectOption label="Option two" value="2" />
    <SingleSelectOption label="Option three" value="3" />
    <SingleSelectOption label="Option nine" value="9" />
    <SingleSelectOption label="Option ten" value="10" />
</SingleSelectField>

• A select can show a Clear button that removes the current selection.
• Use a clearable select if there isn't a None choice in the options.

Prefix

Demo

<SingleSelectField prefix="Data type" selected="3">
    <SingleSelectOption label="Data element" value="1" />
    <SingleSelectOption label="Event data item" value="2" />
    <SingleSelectOption label="Program indicator" value="3" />
    <SingleSelectOption label="Option ten" value="10" />
</SingleSelectField>

• A select can show a label that prefixes the chosen option label.
• Use a prefix when there is limited space and a label above the select would take up too much space.
• Prefix labels should be short and clear.

State: Error

Demo

<SingleSelectField
    error
    validationText="That value is wrong. Sorry!"
    label="Label"
>
    <SingleSelectOption label="Option one" value="1" />
    <SingleSelectOption label="Option two" value="2" />
    <SingleSelectOption label="Option three" value="3" />
    <SingleSelectOption label="Option ten" value="10" />
</SingleSelectField>

• Use an error state if there's a problem with the chosen option, or if it's required but empty.
• Don't show an error too early, give the user a chance to make a choice.
• The error text should help the user fix the problem. Refer to the error writing guidelines for examples.

State: Disabled

Demo

<SingleSelectField disabled label="Label">
    <SingleSelectOption label="Option one" value="1" />
    <SingleSelectOption label="Option eight" value="8" />
    <SingleSelectOption label="Option nine" value="9" />
    <SingleSelectOption label="Option ten" value="10" />
</SingleSelectField>

• Use a disabled state if the select temporarily can't be used.
• Show a Tooltip on hover or focus to explain why the select is disabled.
