Select

sap.m.Select

Intro

The select control (also known as a dropdown) is commonly used to enable users to select an item from a predefined list.

Usage

Use the select control if:

Users need to select one item exclusively from a short list of options (usually between 2 and 12 items).
The values of the option list are of secondary importance and do not need to be displayed right away.

Do not use the select control if:

Users need to choose between two options, such as On or Off and Yes or No. In this case, consider using a switch control instead.
Users need to pick one item from a very large set of options. In this case, consider using the combo box instead.
You need to display more than one attribute. In this case, consider using the input field with a select dialog or a value help dialog instead.
The user needs to search on multiple attributes. In this case, consider using the input field with select dialog or value help dialog instead.
Your use case requires all available options to be displayed right away, without any user interaction. In this case, consider using radio buttons or a radio button group instead.

Information

For more information on which selection control to choose, see the selection control overview.

Responsiveness

The display of the select control depends on the device:

On smartphones, the selection list takes up the whole screen.
On desktop and tablet devices, it appears as a popover. If there is not enough space to show the option list below the field, it opens above the field.

Layout

The select control can be placed in toolbars, such as chart toolbars, footer toolbars, or header toolbars, as well as in forms or tables:

Components

Select Trigger

The trigger to open the option list is either the Select field (1), which also displays the current selection, or an icon (3).

Option List

The option list (2) displays all the items available to the user. The selection is always highlighted. Selecting another option from the list moves the highlight to the selected option.

Full Screen Title Bar for Size S

Opening the select control on a smartphone brings up the option list in full screen mode. The full screen mode can be closed using the icon on the top right corner (5).

You need to set a title for the full screen mode (4). We recommend the following format:

Single selection

Select [Entity]

Example: Select Product

Multi-selection

Select [Entities]

Example: Select Products

Behavior and Interaction

Clicking

The Select field always displays the current selection. The user clicks the field to display a list of options to choose from. Once the user selects an option, the list box closes and the selected option is displayed in the field. If there is no Select field but an icon, the user clicks the icon to open the list of options. The currently selected item is always highlighted in the list to help the user identify what has been selected.

Guidelines

Option List

The option list can contain either text-only values or text values with an icon in front. Keep the text values as short as possible.

Only use icons if they help users better identify or understand the options. To set icons, use the icon property for each list entry.

Do not disable values. In most cases, it is completely unclear how to enable them. Hide the values instead.

If you need to indicate that none of the selection options are selected, or you need to allow users to not select an option, offer an appropriate option, such as (Not Selected) or (No Values Selected). Show this option in parentheses and place it at the beginning of the list. For more examples, see the UI text guidelines.

When using the select control to select filter values: If you need to indicate that all items apply, provide All as an option and place it at the beginning of the list.

If your use case requires a blank input field instead of (None), use a combo box instead.

If the select control is placed in a toolbar with an icon as a trigger for sorting, grouping or filtering a set of items, use the texts below for the “not selected” option.

Sort, Group, and Filter:

(Not Sorted)
Note: In most cases, this option is not necessary; just show the default sort settings instead.
(Not Filtered)
(Not Grouped)

For more information about the toolbar, see the toolbar overview.

Define a default selection whenever possible. If the selected item is not specified, the first one is selected.

Label

The select control can be displayed with or without a label. If the field is attached to another field, you do not need to define a second label.

Information

Do not provide a blank value to indicate that nothing is selected.

Sorting

The sort option list contains all the items that are available to the user. Choose one of the following styles to order the content:

Logical: Sort items into a meaningful order. Group related options together and show the most common options first, followed by less common options. Sort the options alphabetically if more than eight select options are available. This helps the user find the right option quickly.

Example of logical sorting

Alphabetical: Sort currencies, names, and similar content alphabetically.

Example of alphabetical sorting

Numeric: Sort numeric values into a sequential order, with the lowest number first.

Example of numeric sorting

Chronological: Sort time-related information into chronological order, with the most recent first.

Example of chronological sorting

Width

The select control is usually used in forms, where the width is determined by the form element or container in which the select control is embedded.

If you need to restrict the width to a defined value, you can set the width accordingly. However, we do not recommend defining a fixed width. Where possible, use layout containers (such as a form, simple form, or responsive grid layout), and define the width via the layout data property.

Do not allow the control to auto-adjust based on the selection.

Information

If the text length is fixed and doesn’t require localization (for example, currency codes), consider reducing the width.

Width of the Option List

By default, the width of the option list adapts to the width of the longest entry. The maximum width of the option list is set to 600 px.

Text Wrap in the Option List

The option list doesn’t support horizontal scrolling. By default, entries that exceed the maximum width of 600 px for the dropdown are truncated. If you expect the dropdown to contain longer entries, we recommend wrapping items in the option list to enable users to read the full text, (property: wrapItemsText). If wrapping is enabled, the text can wrap to multiple lines.

Unit of Measurement

You can use the layout options of the form to can add the unit of measurement (UoM) after select. Apps can use the label-field ratio to show the UoM after the field. However, you must make sure that the UoM is properly visualized and doesn’t wrap to the next row.

Developer Hint

For accessibility purposes, you can use “ariaDescribedBy” from the input control.

Semantic Colors

Different value states or meanings can be indicated by using semantic colors. The visual states are shown below in their regular state (left) and focused (right). Note that the positive/success state does not show a message on focus.

For more details on the correct usage, see How To Use Semantic Colors.

Neutral

Value State Text

The select control can display the value state text even if the dropdown is open. This ensures that the value states are shown in all situations and on all devices. When the user opens the dropdown, the value state sticks to the top and does not scroll away. The control also supports multi-line text for the value state.

Read-Only

The select control can be displayed as read-only (property: editable, default = “true”). If the editable property is set to “false”, the value of the select cannot be changed. The control remains focusable, but the background and border are changed to indicate that it is read-only.
