class Primer::Alpha::ActionMenu

Additional information around the keyboard functionality and implementation can be found on the [WAI-ARIA Authoring Practices](www.w3.org/TR/wai-aria-practices-1.2/#menu).
The action for the menu item needs to be on the element with ‘role=“menuitem”`. Semantics are removed for everything nested inside of it. When a menu item is selected, the menu will close immediately.
@accessibility
The only allowed elements for the `Item` components are: `:a`, `:button`, and `:clipboard-copy`. The default is `:button`.
ActionMenu is used for actions, navigation, to display secondary options, or single/multi select lists. They appear when users interact with buttons, actions, or other controls.

def initialize(

Parameters:
  • system_arguments (Hash) -- <%= link_to_system_arguments_docs %>.
  • form_arguments (Hash) -- Allows an `ActionMenu` to act as a select list in multi- and single-select modes. Pass the `builder:` and `name:` options to this hash. `builder:` should be an instance of `ActionView::Helpers::FormBuilder`, which are created by the standard Rails `#form_with` and `#form_for` helpers. The `name:` option is the desired name of the field that will be included in the params sent to the server on form submission.
  • select_variant (Symbol) -- <%= one_of(Primer::Alpha::ActionMenu::SELECT_VARIANT_OPTIONS) %>
  • dynamic_label_prefix (String) -- If provided, the prefix is prepended to the dynamic label and displayed in the show button.
  • dynamic_label (Boolean) -- Whether or not to display the text of the currently selected item in the show button.
  • preload (Boolean) -- When true, and src is present, loads the `include-fragment` on trigger hover.
  • src (String) -- Used with an `include-fragment` element to load menu content from the given source URL.
  • size (Symbol) -- <%= one_of(Primer::Alpha::Overlay::SIZE_OPTIONS) %>.
  • anchor_side (Symbol) -- <%= one_of(Primer::Alpha::Overlay::ANCHOR_SIDE_OPTIONS) %>.
  • anchor_align (Symbol) -- <%= one_of(Primer::Alpha::Overlay::ANCHOR_ALIGN_OPTIONS) %>.
  • menu_id (String) -- Id of the menu.
