Allow multiple records attach

This will help with attaching multiple records from the same modal.

The suggestions could be added as a DSL option

field :memberships,
  as: :has_many,
  attach_suggestions: -> do
	# this would feed of the regular query that's being made to fetch the suggestions
    query.where.not(user_id: parent.id).or(query.where(user_id: nil))
  end

• The results should be displayed using the title attribute set on the resource
• If the resourse has the search description set, display that
• same for avatar
• when the user selects a few suggestions and clicks attach, we call to a new controller method to execute that logic
