Propiedad en script no detectada en navegadores.........

[cmt_rodrigo]

....IE 8 y Firefox. En IE7 y anteriores va bien.

Se trata de un menú desplegable con sombreado. La capa div que soporta el sombreado NO se ajusta al contenido de los desplegables, en resumidas cuentas, no detecta lo siguiente:

TransMenu.menuPadding = 0

he probado a ponerle padding negativo pero sin resultado.

¿Alguna idea por favor?

Gracias de antemano.

Muchas veces pasa, que en algunos navegadores y/o versiones diferentes, hay que establecer el alto de la capa (height) porque si no, esta capa se reduce y no alcansa a cumplir su funcion, suerte

esto se hace en la CSS, poniendo en la capa correspondiente:

#ejemplo {width: 200px;height:100px}

Uf....he probado pero sin suerte.

Efectivamente puedo variar la altura del desplegable pero los items o secciones se adaptan y también crecen y por tanto el fallo persiste.

Si quieres echarle un vistazo y tienes IE8 o Firefox visita:

Gracias de antemano

Amigo pasa los códigos que as modificado.
Yo estoy usando el mismo menú que tu en mi pagina y ami me funciona bien en todos los exploradores

OK, será más fácil así supongo. Aquí los tienes a ver si ves algo raro:

La hoja de estilo de los menús:

.transMenu {

/* this is a hack for mac/ie5, whom incorrectly cascades the border properties of the parent table to each row */
border:none;
cursor:pointer;
cursor:hand;
}

/* this DIV is the semi-transparent white background of each menu. the -moz-opacity is a proprietary way to get transparency in mozilla, the filter is for IE/windows 5.0+. */
/* we set the background color in script because ie mac does not use it; that browser only uses a semi-transparent white PNG that the spacer gif inside this DIV is replaced by */
.transMenu .background {
position:absolute;
left:0px;
top:0px;
z-index:1;
-moz-opacity:.0;
filter:alpha(opacity=95)}

/* same concept as .background, but this is the sliver of shadow on the right of the menu. It's left, height, and background are set by script. In IE5/mac, it uses a PNG */
.transMenu .shadowRight {
position:absolute;
z-index:3;
top:3px; width:2px;
-moz-opacity:.4;
filter:alpha(opacity=40);
}

/* same concept as .background, but this is the sliver of shadow on the bottom of the menu. It's top, width, and background are set by script. In IE5/mac, it uses a PNG */

.transMenu .item.hover {

color:#FFFFFF;
}

/* this is either the dingbat that indicates there is a submenu, or a spacer gif in it's place. We give it extra margin to create some space between the text and the dingbat */
.transMenu .item img {
