Dropdown actions for index

[lporras]

When adding many custom actions using index as table you get a large column for actions. This adds a 'dropdown' option to actions method in order to display the actions in a dropdown menu

Some Examples:

To list default actions and customs actions:

index do
  selectable_column
  column :title
  actions dropdown: true do |post|
    item "Preview", admin_preview_post_path(post)
  end
end

To list custom actions without default_actions:

index do
  selectable_column
  column :title
  actions dropdown: true, default: false do |post|
    item "Preview", admin_preview_post_path(post)
  end
end

I see you repurposed an existing test, but there should really be three different tests:

# 1
actions defaults: false
# 2
actions dropdown: true
# 3
actions dropdown: true, defaults: false
