Usage

Use tabs to help users navigate information while staying on the same page. Text labels and content in the panel should be related so users know what to expect when they select each tab. Never force users to switch back and forth between tabs to complete a task.

When to use tabs

Use tabs to organize lots of information into logical sections. Consider using an accordion if that information needs to be viewed simultaneously because using tabs is not suitable as it forces users to rely on short-term memory when switching back and forth. Using an accordion can also accommodate more sections with longer text labels whereas tabs should only display three or four sections with short text labels. Therefore, if viewing lots of sections of content simultaneously is critical to the user experience or if important information requires more focus and less clicking, use an accordion instead.

Tabs vs. accordion

Tabs allow users to click through content one section at a time whereas an accordion allows users to view multiple sections of content simultaneously.

Number of tabs

To reduce cognitive load and a cluttered user interface, avoid using more than three or four tabs.

Variants

When choosing one variation over the other, consider where it is being used. If using tabs multiple times on one page, use one variation only. Open tabs - use if you want to keep your design clean and maintain a minimal look and feel Box tabs - use if your design includes a lot of boxes or you want to maintain the classic tabs look and feel

Orientation

When choosing one orientation over the other, consider the content in the panel, other elements in the layout, and how you want users to read the content: Horizontal tabs are placed in the middle of a container and offer users a top-to-bottom reading experience Vertical tabs are placed on the left side of a container and offer users a left-to-right reading experience

Alignment

If using horizontal tabs, the default orientation is left aligned, but center aligned is also an option.

Inset and tab panel spacing

An inset is used to ensure consistent alignment and padding between text labels, overflow buttons, and content in the panel.

Helpful Tip

With horizontal tabs, there are two inset options. With vertical tabs, there is only one.

Certain content layouts may require removing the inset. While this is not a default style, it is possible with custom CSS.

Logos

In certain edge cases, logos can be used instead of text labels.

Tab panel

The panel is below or to the right of tabs. Use this area to place other elements or content like text, links, calls to action, and more. Text blocks should not exceed 750px to maintain optimal readability.

Warning

The Tabs element has no control over the panel in terms of content, layout, spacing, etc.

Writing content

Text labels

Text labels should be concise, scannable, and descriptive of content in the panel. They should not exceed more than two or three short words. If they do, work with a content strategist to shorten them.

Character count

In general, tabs should have three or four text labels maximum. Text labels should be short but descriptive.

Layout

Horizontal tabs width

The divider line can be set to any width or be the same width as the list of tabs.

Vertical tabs height

The divider line will become taller if the height of content in the panel exceeds the height of vertical tabs.

Card

Tabs can be used in a card if the layout is wide enough and there are fewer tabs.

Behavior

Overflow

If the number of tabs exceeds the container width or breakpoint, overflow buttons with chevron icons are added to each side so users can horizontally scroll to reveal hidden tabs.

Warning

Long text labels will make overflow buttons appear sooner, try and write text labels as short as possible.

When the first tab is active, the left overflow button is disabled. When the last tab is active, the right overflow button is disabled. When a tab that is cut off is selected, the list of tabs shifts so the selected tab is in full view.

Responsive design

Large breakpoints

Small breakpoints

Vertical tabs switch to horizontal tabs with overflow buttons on small breakpoints.

Best practices

Not enough tabs

There should be at least two tabs minimum.

Too many tabs

Be careful about displaying too many tabs, some of them will become hidden even at large breakpoints.

Extra spacing

Do not add extra spacing or stretch the width of tabs.

Overflow buttons

Overflow buttons should not be visible if all tabs are visible.
