php - 将 php 中的列表/菜单更改为类似于文本字段但仍从 mysql 数据库填充数据

Question

下面是我的代码，它工作正常。但是，如何从选择更改为说 TEXT 字段以便可以键入，而优先级列在组合框中？

<?php
$con=mysqli_connect("localhost","root","","databasse");

if (mysqli_connect_errno($con)) {
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

else {
    echo "Select Region: ";
    echo "<select name='RegName' id='RegName'>";
    $query = "SELECT * FROM rtable";
    $result = mysqli_query($con,$query);
    //echo "<option value='userid'>All</option>";

    while($row = mysqli_fetch_array($result)) {
        echo "<option value='RegName'>".$row['RegName']." </option>";
    }
    echo "</select>";
?>
