Description

Lists are continuous, vertical indexes of text and images.
They are composed of items containing primary and in some cases supplemental information, which can be shown as text, icons, or images.
The component may be part of a page layout or in a Popover. They also often appear as a sub-component within a larger element, such as a Drop-down Menu, Drag and Drop, or Combo Box.

Usage & Behavior

General guidelines

Structure

List items must have a label, with the main object name. If the entire name does not fit, it can be truncated and a Tooltip can be used on hover.
List items can optionally also have:
- A leading icon. These should only be used if the list can contain several types of objects. If all items are of the same type, an icon should not be used.
- A leading image.
- Up to 2 secondary lines of text. Secondary lines cannot have their own leading icons or images.
- Extra metadata, such as a tag, text, or an icon. These should be positioned to the right of the item, centered vertically.
- Up to 2 action icons, such as delete. These should only appear on hover or when an item is selected. They should be positioned to the right of the item, centered vertically (replacing the extra metadata, if exists).
For lists which support multi-select, the number of selected items will be displayed in brackets to the right of the total number of items. If no item is selected it should display “(0 selected)”.

Lists can also have:
- A preceding label at the top of the list, showing the total number of items included in the list.
- A Search field on long lists, allowing users to find items easily.
- A pagination component

Internal Logic

Lists should be ordered in logical ways that make the content easy to scan. Order the list using one of these rules:

Alphabetical. If there are more than 8 options available, sort them alphabetically. This helps the user to find the right option quickly. Sort currencies, names, and similar content alphabetically.
Numeric. Sort numeric values in a sequential order, with the lowest number first.
Chronological. Sort time-related information into chronological order, with the most recent first.

Interaction

On hover, the row will be highlighted and Checkboxes or Icon Buttons will appear, where applicable.
When the label is truncated (item name), hovering over it will show a Tooltip with the full label.
Items in the header area, including the search bar and list title, should remain sticky when the list is scrolled.

Selection

There are three possible selection modes:

Interaction

Screenshot

Single Selection

Only one item can be selected.
Clicking anywhere on the item row will select it.
One item must always be selected.
Selecting an item will automatically deselect the previously-selected item.

Multi-select checkboxes

Clicking on any checkbox or anywhere on the item row will select or deselect the corresponding item.
Items can also be selected by holding the ctrl or shift keys on the keyboard and clicking anywhere on the item.

Smart Selection

On hover anywhere over an item, a checkbox appears.
Clicking anywhere on the item row will select it. As with Single selection, selecting an item in this way will automatically deselect the previously-selected item.
Additionally, the user can select multiple items in one of two ways:
- By directly checking any item checkboxes.
- By holding the ctrl or shift keys on the keyboard and clicking anywhere on the item.
When relevant, an Apply button will appear, allowing the user to apply the selected items.

Search

When the list includes a search field and the user starts typing the characters, the text “<number> found” or “<number> found out of <total no.>” will be displayed instead of the total no. of items.

Best practices

Use:

when there is a need to select one or more items from a list.
when you want to show relevant content for each list item.
when content may vary between rows (contrary to a data table, which is more strict in nature).

Don’t use:

For long, complex lists where grouping and categorisation could be applied → use a Tree.
For items with multiple attributes which need to be displayed → use Data Tables.

General:

An optional Search field can be used for long, scrolling lists, to help the user find items easily.
Visual elements, such as leading icons and images, can help the user to scan and grasp a large amount of information.

Accessibility compliance

Unless otherwise specified, see our general compliance information in Fundamentals - Accessibility.
