Internal Logic
Logical ordering - Lists should be sorted in logical ways that make content easy to scan, such as alphabetical, numerical, chronological, or by user preference.

...
Clicking a single list item will select it.

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)”.
Single-line list | Two-line list | Three-line list | |
|---|---|---|---|
Full list |  | |  |
Single Item |  |  |  |
Single item with icon / image |  |  |  |
Single item with multi select |  |  |  |
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.
...
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

When the label is truncated (
...
item name), hovering over it will show a
...
Tooltip with the full label
...
Selecting:
...
.
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 |
|
...
Multiple selections: Allow the selection of one or more items. For this, the list provides checkboxes on the left side of each line item. Each item is selected independently of the others
Single Selection | Multiple Selection Mode |
|---|---|
Single selection is activated by selecting the node label. Selecting the node label will select the node and un-select previously selected node. | On mouse hover a node, a check box is displayed. If the user checks it he is placed in a multi selection mode. Multi selection mode can also be activated by using Ctrl/Shift while selecting the node label. |
Scrolling:
wide lists/long tables - sticky areas. When the user scrolls, the title and the filter info bar can stick to the top of the surrounding layout container
Mouse wheel should work on scroll.
Best practices
Use data lists when
A flexible layout is more important than arranging information in a grid
You want to include active content like a chart
Content displayed may vary between rows
Don’t use
For a more complex and longer lists grouping and categorisation can be applied (see Tree view)
For more complex items with multiple attributes that should be displayed use Data Tables
Other principles
Actionable - Lists present content in a way that makes it easy to identify a specific item in a collection and act on it.
Searchable- When a list is really long (more than the visible container)and a slider is displayed beside the list . the sorting and the grouping alone are not sufficient and search should be applied (see search)
Accessibility compliance
Each component should be A11y complied, please follow the 3 guidelines linked below. At the very least we should document that each component is in compliance with each of the 3
Focus management
We already set a general guidelines described in Keyboard & Focus Management Guidelines
Screen reader support
Make sure the components support screen reader for content or behavior where needed - see Screen Reader Guidelines

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.
