Here is a sample code

index.php
[code]<?

// Edit these values {{{

$sql_host = 'localhost';
$sql_user = 'root';
$sql_pass = '';
$sql_db        = 'test';

// }}} End edit

?>

<script language="JavaScript">

    var arItems = new Array()

    arItems = [

    <?

    mysql_connect($sql_host, $sql_user, $sql_pass);
    mysql_select_db($sql_db);

    $qry = mysql_query('SELECT * FROM temp WHERE parent > 0');

    while ($row = mysql_fetch_array($qry)) {
        $arr.= '[' . $row['parent'] . ', ' . $row['id'] . ', \'' . $row['name'] . '\'],' . "\n\t";
    }

    $final = substr($arr, 0, -3);
    echo $final;

    ?>

    ]

    function fillItems( intStart ) {

        var fTypes = document.form1.types
        var fItems = document.form1.items
        var a = arItems
        var b, c, d, intItem, intType

        if ( intStart > 0 ) {
            for ( b = 0; b < a.length; b++ ) {
                if ( a[b][1] == intStart ) {
                intType = a[b][0];
            }
        }

        for ( c = 0; c < fTypes.length; c++ ) {
            if ( fTypes.options[ c ].value == intType ) {
                fTypes.selectedIndex = c;
            }
        }
    }

    if ( intType == null ) {
        intType = fTypes.options[ fTypes.selectedIndex ].value
    }

    fItems.options.length = 0;

    for ( d = 0; d < a.length; d++ ) {
        if ( a[d][0] == intType ) {
            fItems.options[ fItems.options.length ] = new Option( a[d][2], a[d][1] ); // no line-break here
        }

        if ( a[d][1] == intStart ) {
            fItems.selectedIndex = fItems.options.length - 1;
        }
    }
   }

</script>

<form name="form1">
<select name="types" onChange="fillItems(0)">
    <option value="#" selected="selected">Please select</option>

    mysql_connect($sql_host, $sql_user, $sql_pass);
    mysql_select_db($sql_db);
    $qry = mysql_query('SELECT * FROM temp WHERE parent = 0');
    while ($row = mysql_fetch_array($qry)) {

        <option value="<?=$row['id'];?>"><?=$row['name'];?></option>
    <?
    }
    ?>
</select>

<select name="items"></select>
