When filtering the custom fields in the "Field Required Validator" page for a workflow, only 20 items are displayed in its search results drop-down.

If there are several fields returned by the filter entered, the User might not see the field as the results displayed might exceed 20 items. This Suggestion was created to increase the number of items displayed on the results drop-down.

Current workaround: type a space after the filter value in the search box.
