Estoy trabajando con un select que me carga las opciones a traves de php y uso ajax. Hay una opción donde no necesito que me carge nada de contenido por lo que lo oculto con esta etiqueta :
style="display:none" Código PHP:

<body>
<table align="center">
<form>
<tr>
<td>Seleccionar entidad</td>
<td><select id="selEnt" name="selEnt" size="1" onchange="ajaxFunction()">
<option value="todo"<? if ($fE=="todo") echo "selected=\"selected\""; ?>> Toda la república</option>
<option value="01" <? if ($fE=="01") echo "selected=\"selected\""; ?> >A</option>
<option value="02" <? if ($fE=="02") echo "selected=\"selected\""; ?> >B</option>

<option value="19" <? if ($fE=="19") echo "selected=\"selected\""; ?> >N</option>
<option value="20" <? if ($fE=="20") echo "selected=\"selected\""; ?> >O</option>
<option value="21" <? if ($fE=="21") echo "selected=\"selected\""; ?> >P</option>
<option value="22" <? if ($fE=="22") echo "selected=\"selected\""; ?> >Q</option>
<option value="23" <? if ($fE=="23") echo "selected=\"selected\""; ?> >Q</option>

</select>
</td>
</tr>
<tr><td></td>
<td>
<div id='ajaxDiv'></div>
</td>
</tr>
<tr><td><input type="submit" /></td></tr>
</form>
</table>
</body>
</html>
Y este es el archivo que me llena las opciones
Código PHP:
<?php
require_once("../comun/conexion.php"); // database connection
// Retrieve data from Query String
$make = $_GET['selEnt'];
//build query
$query = "SELECT municipio,nom_mun FROM inm_domicilio_carlos WHERE entidad = '$make' group by nom_mun";
$result = @mysql_query($query);
$rowEstados = mysql_fetch_array($result);
/////////////////////////////////////////////////
//esta parte funciona con firefox pero no con ie7
if($make == 'todo')
echo "<td style=\"display:none\"></td>";
//////////////
else
{
//Build Result String
$dropdown = "<select name=\"selMun\">";
$dropdown .= "<option value=\"\">Seleccione Municipio</option>";
// Insert a new row in the table for each person returned
do {
$dropdown .= "<option value=".$rowEstados['municipio'].">".$rowEstados['nom_mun']."</option>";
}while ($rowEstados = mysql_fetch_array($result));
$dropdown .= "</select>";
echo $dropdown;
}
?>
Hay alguna restricción para usar la instrucción display???
