ActionGroup
An ActionGroup is a grouping of ActionButtons that are related to one another.

Example#
Content#
ActionGroups accept a list of Item elements as children, each with a key prop. Alternatively, a function that returns Item elements is also supported. See the collection components docs for more details about this API.
Icons#
Icons can be added to ActionGroup items by wrapping the label in a Text element, and adding the icon as a sibling.
You can also hide the label text within the buttons using the buttonLabelBehavior prop. When set to "hide", the label is
hidden and automatically shown in a tooltip on hover.
Accessibility#
Icon only ActionGroups should usually include a tooltip to describe the button via the buttonLabelBehavior prop as described above. This also automatically handles
labeling the button for assistive technology users.
In rare cases where no tooltip is desired, an alternative text label must be provided to identify the control for accessibility.
This should be added using the aria-label prop to each Item.
Internationalization#
In order to internationalize an ActionGroup, the content provided to all child items should be localized.
Selection#
ActionGroup supports multiple selection modes. By default, selection is disabled, however this can be changed using the selectionMode prop.
Use defaultSelectedKeys to provide a default set of selected items (uncontrolled) and selectedKeys to set the selected items (controlled). The value of the selected keys must match the key prop of the items.
See the react-stately Selection docs for caveats regarding selection prop typing.
The selectedKeys prop can be used to make the selected state controlled.
Set selectionMode prop to multiple to allow more than one selection.
Events#
Use the onSelectionChange prop as a callback to handle press events on items when selectionMode is either single or multiple.
The key prop from the selected item will be passed into the callback.
To continue to capturing actions when selectionMode is none, utilize the onAction prop.
Collapsing behavior#
By default, ActionGroup items wrap to form a new line when horizontal space is limited. However, this can cause content to shift below the
ActionGroup. If the ActionGroup should always appear in a single line, the overflowMode prop can be set to collapse. In this mode, when
horizontal space is limited, the ActionGroup will collapse into a menu. The exact behavior depends on the selectionMode.
Non-selectable#
When selection is not enabled, ActionGroup displays as many items as possible and collapses the remaining items into a more actions menu.
Selection#
When selection is enabled, ActionGroup collapses all items into a menu together when space is limited. The menu button indicates when one of
the options within it is selected by showing a highlighted state. A summaryIcon should be specified to visually communicate the purpose of
the ActionGroup when collapsed, and an aria-label should be provided to describe the ActionGroup to assistive technology.
This example shows a multi-selectable ActionGroup that can be used to select text styles. When space is limited, it collapses into a dropdown
menu, and displays the TextStyle icon passed to the summaryIcon prop.
Single selection#
A special case where a summaryIcon is not needed is a single selectable ActionGroup (selectionMode="single") which enforces that an item
is always selected (disallowEmptySelection). In this case, the selected item is displayed inside the menu button when collapsed.
Collapsing button labels#
In addition to collapsing items that don't fit into a menu, the button labels can also be automatically hidden when space is limited.
This keeps more buttons visible at a time before needing to collapse into a menu. This behavior can be enabled by setting the
buttonLabelBehavior prop to "collapse". The labels will be automatically shown in tooltips when collapsed.
Vertical collapsing behavior#
Non-selectable vertical ActionGroups also support collapsing when the height is too small to fit all of the buttons. The behavior is the same as for horizontal ActionGroups, except for the positioning of the tooltips and menu.
Vertical ActionGroups with selection do not currently support collapsing. When selection is enabled, we recommend placing the ActionGroup in a scrollable container so that the user can access all items.

Visual options#
Quiet#
Emphasized#
The additional styling provided by the isEmphasized prop is only applied when items are selected.
Static color#
The staticColor prop can be used when the ActionGroup is displayed over a color background. When selected, the icon and text in each
button automatically take on the color of the background. You are responsible for choosing the static color variant that ensures the
text meets an accessible contrast ratio
with the background.
Disabled#
To disable the entire ActionGroup, use the isDisabled prop on the root.
To disable individual items, a list of disabledKeys can be provided.
Orientation#
Using the orientation prop with value vertical changes the alignment of the items to follow the y-axis.
Density#
Using the density prop with value compact changes the margins between the buttons.
In the default case, this merges the borders of neighboring ActionButtons. In the
quiet case, it just reduces the margin size between the buttons.
Justified#
The isJustified prop will divide all available horizontal space evenly among the buttons.
