Usage
Multi Button VS Action Button
On Multi Buttons, the action will trigger as soon as an item in the menu is clicked, contrary to Action Buttons which let users select an option in the menu without executing said option.
Unlike the Action Button, there is no “default” action.
When to use a Basic Button VS Multi Button
Use when related actions can be grouped in a dropdown.
Use the Multi Button when multiple action options are available (especially if the actions are all considered primary). This may be particularly helpful when there is a lack of real estate.
Avoid listing out the individual action options with basic buttons. This is especially true of the primary button as there should only be 1 primary button per application area.
Use the basic button when there is only 1 action option available.
Avoid using the Multi Button when there is only 1 action option available.
Use concise labels
Use clear and to-the-point language.
Limit the label length and do not use punctuation marks.
Use unambiguous text
Unless the context around the multi-button is clear, the multi-button text should be direct about the outcome of the action.
Unless the context is clear, avoid ambiguous text.
