Method: Primer::Alpha::ActionList#build_item

Defined in:
app/components/primer/alpha/action_list.rb

#build_item(component_klass: ActionList::Item, **system_arguments) ⇒ Object

Builds a new item but does not add it to the list. Use this method instead of the ‘#with_item` slot if you need to render an item outside the context of a list, eg. if rendering additional items to append to an existing list, perhaps via a separate HTTP request.

Parameters:

  • component_klass (Class) (defaults to: ActionList::Item) —

    The class to use instead of the default <%= link_to_component(Primer::Alpha::ActionList::Item) %>

  • system_arguments (Hash) —

    These arguments are forwarded to <%= link_to_component(Primer::Alpha::ActionList::Item) %>, or whatever class is passed as the ‘component_klass` argument.
