You can add auto suggestion in search box that allows you to type the text and based on text, records will be shown as suggestion. You can enable/disable auto suggestion in config file. Please note that auto suggestion works with specific column not for "All" option in column dropdown of search box. You need to type atleast 2 character to view auto suggestion search result.
//enable the auto suggestion and hide the "All" text from the search box
$pdocrud = new PDOCrud(false, "", "", array("autoSuggestion" => true, "showAllSearch" => false));
echo $pdocrud->dbTable("orders")->render();
