+Feature: Searchable fields
+  As a CMS user
+  I want searchable dropdown fields to function when used in a content block
+  So that I can continue to update my content
+
+  Background:
+    Given I add an extension "DNADesign\Elemental\Extensions\ElementalPageExtension" to the "Page" class
+    And a "page" "Blocks Page" with a "My block" searchable fields block
+    And a "test-1" searchable fields object
+    And a "test-2" searchable fields object
+    And a "test-3" searchable fields object
+    Given the "group" "EDITOR" has permissions "Access to 'Pages' section"
+    And I am logged in as a member of "EDITOR" group
+    And I go to "/admin/pages"
+    And I left click on "Blocks Page" in the tree
+    When I see a list of blocks
+    Then I should see "My block"
+    When I click on block 1
+
+  Scenario: I can use lazy-loaded searchable dropdown fields
+    When I click on the "#Form_ElementForm_1_PageElements_1_ElementalSearchableFieldsObjectID .ss-searchable-dropdown-field__value-container" element
+    And I type "test-1" in the field
+    And I wait 2 seconds
+    And I press the "Enter" key globally
+    When I click on the "#Form_ElementForm_1_PageElements_1_ElementalSearchableFieldsObjects .ss-searchable-dropdown-field__value-container" element
+    And I type "test-2" in the field
+    And I wait 2 seconds
+    And I press the "Enter" key globally
+    And I type "test-3" in the field
+    And I wait 2 seconds
+    And I press the "Enter" key globally
+    When I press the "View actions" button
+    And I press the "Save" button
+    And I wait 1 second
+    Then I should see a "Saved 'My block' successfully" success toast
+    And I should see "test-1"
+    And I should see "test-2"
+    And I should see "test-3"
