Description

A drop-down menu consists of related content grouped together and organized vertically.

It allows users to select one or multiple values from a list of predefined values. An optional search field can help the user to find values easily.

Usage & Behavior

General guidelines

Structure

The drop-down consists of:

Trigger area - selecting the drop-down trigger should open or close the options list. Includes:

a text area, with the currently-selected option(s) or default text.
a drop-down arrow.

Options list - displays the list of available values, consisting of:

Options - must include a text label, but can additionally have an icon. Keep the labels short, because the list uses single lines only.
In case selecting an option is not mandatory, a No selection item should appear at the top of the options list. This will allow users to avoid selection or deselect a previously selected option.
Selection indicator - a blue check mark should be shown to the left of the selected option.
Action icons (optional) - these add extra actions for each list option, and appear on user interaction.
Status icons (optional) - these add extra information for each list option and always appear.
Dividers or group headers may also be used to organise the options list.

Default State

The drop-down trigger area consists of a text box showing the default option, if one exists. For example:

Verint LUX Design System > Drop-down Menu > DDMenu Label.png

If there is no default option:

Where a preceding label is being used, the default text will be Select.

Verint LUX Design System > Drop-down Menu > DDMenu Label 2.png

Where there is no label, the default text will be Select a {NameOfEntity}. For example, Select a Job Title.

Verint LUX Design System > Drop-down Menu > DDMenu Label 3.png

Content

When possible, a drop-down menu should have a preceding label. Labels inform the user about what is included in the options list.

Order the options list using one of these rules:
- Logical. Sort options into a meaningful order. For example, group related options together, and order by the most common to least common.
- 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.
The width of the options list should adapt to the longest option, up to a maximum width. Where options are too long they should be truncated with a tooltip displaying the full text shown on hover.

Internal Logic

Users need to select one option exclusively from a short list (where the user can select multiple options, see Multi-select drop-down below).
There should be a minimum of 3 options.
The user may select an item either by using the mouse and clicking, or by using the Up and Down keys to navigate between options and Enter to select.
On selection of an option, the options list will close.
The selected option will be shown in the trigger area.

Searchable drop-down

A Search field should be added:

to options lists with over 15 items.
when users are likely to know what they are looking for.

Internal Logic

The search field will be auto-focused when the options list opens, so that the user may start searching immediately.
The search field will operate as a Live Search.
The user may select an item either by using the mouse and clicking, or by using the Up and Down keys to navigate between options and Enter to select.
On selection, the options list will close.
The selected item will be presented in the trigger area.
The search field is cleared each time the options list is closed.

Interaction

Interaction	Visual	Details
Click the trigger area		Clicking or tapping anywhere on the trigger area opens or closes the options list. The search field is focused so that the user may start typing.
Enter search		As characters are entered, the list is filtered to show matching results only. Unless otherwise specified, the filter can match anywhere within the value string (at the beginning, middle or end). The part of the option label which matches the search string should be shown in bold. The user may use the Up and Down keys to navigate between options and Enter to select.
Select an option		On selecting an option: the options list closes. the selected option is displayed in the field. the search field is cleared.
View options list with an existing selection		Shows the selected item with a blue check mark on the left side of the option.

Multi-select drop-down

A multi-select drop-down allows users to easily select multiple values from a predefined list.

Internal Logic

Selected items

The selected values are presented in the trigger area as read-only.
2 or more items are presented one after the other, separated by a comma and a space.
When the selected values exceed the size of the trigger area, the labels will be replaced by the total number of selections, for example “5 selected“.
An option can be selected by clicking on the checkbox or the label.
When space is limited and/or the user is expected to select several items, a Select All option can be added.

Select All (optional)

Verint LUX Design System > Drop-down Menu > Menu Samp All 1 Copy 2.png

Verint LUX Design System > Drop-down Menu > Menu Samp All 1 Copy.png

Verint LUX Design System > Drop-down Menu > Menu Samp All 1.png

The All option is a master type checkbox, which controls the state of all the other checkboxes in the list. See Checkbox for the full behaviour.
The All option should be presented at the top of the options list.
When all items are selected, the trigger area should show All instead of a number.

Use the All option when:

The user is expected to select all or most of the items.
The list is very long (so it will allow the user to easily clear all selections).

Interaction

Interaction	Visual	Details
Click the trigger area		Clicking or tapping anywhere on the trigger area opens or closes the options list.

Best practices

Use when:
- The options list is small-medium in size.
- Space is constrained.
Use the searchable type when:
- there are more than 15 options.
- when users are expected to know what they are looking for, and are likely to be aware of how the option is labelled.
Don’t use when:
- The list has fewer than 3 options.
- The list has fewer than 7 options and the user needs to see them all at once → use /wiki/spaces/UX/pages/299860272 or Checkboxes instead.
- The user needs to enter a value which is not in the list → use a /wiki/spaces/UX/pages/299860272 instead.
- The list is large → use Dual List Selector or List instead.
General:
- Only show a scrollbar when the list has over 8 items.
- Keep the text values as short as possible, because the list uses single lines only.
- There is no horizontal scrolling in the option list.
- The options list should adapt its length to the longest entry by default, but values which are too long may be truncated, with a tooltip displaying the full text (not recommended).
- Place options that represent All or None at the beginning of the list, regardless of the sort order of the remaining items.
- Do not allow the control to auto-adjust based on the selection.
- If there’s no preceding label, or if the label is not indicative enough, the {NameOfEntity} should be added within the drop-down, after the number of selections. For example, 2 categories selected:

Accessibility Compliance

Focus management

If a search bar exists, it will be treated as the first item on the options list.
