-#### Inlining Ajax Options in Feature Tests
-
-When writing UI driven feature specs (i.e. with Capybara),
-asynchronous loading of select options can increase test
-complexity. `activeadmin-searchable_select` provides an option to
-render all available options just like a normal select input while
-still exercsing the same code paths including `scope` and
-`text_attribute` handling.
-
-For example with RSpec/Capybara, simply set `inline_ajax_options` true
-for feature specs:
-
-```ruby
-  RSpec.configure do |config|
-    config.before(:each) do |example|
-      ActiveAdmin::SearchableSelect.inline_ajax_options = (example.metadata[:type] == :feature)
-    end
-  end

-### Passing options to Select2
-
-It is possible to pass and define configuration options to Select2
-via `data-attributes` using nested (subkey) options.
-
-Attributes need to be added to the `input_html` option in the form input.
-For example you can tell Select2 how long to wait after a user
-has stopped typing before sending the request:
-
-```ruby
-   ...
-   f.input(:category,
-           as: :searchable_select,
-           ajax: true,
-           input_html: {

 This will generate the path for fetching as `all_options_admin_option_type_option_values(option_type_id: f.object.product.option_type_id)` (e.g. `/admin/option_types/2/option_values/all_options`)
