Constructor Details

#initialize(tag: DEFAULT_TAG, align: ALIGN_DEFAULT, tooltipped: false, body_arguments: {}, **system_arguments) ⇒ AvatarStack

Returns a new instance of AvatarStack.

Parameters:

  • tag (Symbol) (defaults to: DEFAULT_TAG) —

    <%= one_of(Primer::Beta::AvatarStack::TAG_OPTIONS) %>

  • align (Symbol) (defaults to: ALIGN_DEFAULT) —

    <%= one_of(Primer::Beta::AvatarStack::ALIGN_OPTIONS) %>

  • tooltipped (Boolean) (defaults to: false) —

    Whether to add a tooltip to the stack or not.

  • body_arguments (Hash) (defaults to: {}) —

    Parameters to add to the Body. If ‘tooltipped` is set, has the same arguments as <%= link_to_component(Primer::Tooltip) %>. The default tag is <%= pretty_value(Primer::Beta::AvatarStack::DEFAULT_BODY_TAG) %> but can be changed using `tag:` to <%= one_of(Primer::Beta::AvatarStack::BODY_TAG_OPTIONS, lower: true) %>

  • system_arguments (Hash) —

    <%= link_to_system_arguments_docs %>
