<?php       
include('include/functions.php');
$Select = "SELECT * FROM category_master";
$Q = mysql_query($Select);
?>
<form name="myForm" method="post">
    <select name="select"> 
<?php  while($row = mysql_fetch_assoc($Q))
        {

        echo "<option value=''> $row[_cat_name] </option>";

        }
?>  
        </select>
</form>
