Sure but only after SMF 2.1 reach at least a second RC, or the final/gold version

That would be nice, but you don't really need to do that.

Regards.
Please tell us if you need more help.

Here you have the PR, just merge it https://github.com/ItalianSpaceAstronauticsAssociation/reseller/pull/1

Sorry I've been busy, I'll help you later today ASAP

I don't know if it's possible.
But one thing we can do is to add the main button as a submenu in the first place in every button that has child buttons.

Don't know if that has sense to you. If not, see our demo site, the Simple Metro or LikeIPB theme

This was solved on smf theme support topic for the ones that are interested.

I don't think that it's a theme issue, but I'll do some research

index.css
.nav-bar .nav-bar-inner > ul.usermenu > li span.name
{
    display:block;
float:left;
color:#ededed;
text-shadow: 0 1px 0 rgba(0, 0, 0, 0.6);
font-size:14px;
text-align: left;
text-decoration: none;
cursor: pointer;
height: 15px;
background: url(../images/md/name_arrow.png) no-repeat right;
padding-right: 20px;
line-height: 32px;
}

Replace with
.nav-bar .nav-bar-inner > ul.usermenu > li span.name
{
    display:block;
float:left;
color:#ededed;
text-shadow: 0 1px 0 rgba(0, 0, 0, 0.6);
font-size:14px;
text-align: left;
text-decoration: none;
cursor: pointer;
height: 15px;
background: url(../images/md/posterarrow.png) no-repeat right;
padding-right: 20px;
line-height: 32px;
}

No te puedo ayudar demasiado, lo mejor es que preguntes en la web de dzinerstudio que es donde se supone que adquiriste ese theme.

Saludos

Tan pronto como haya tiempo y sea posible.

Si tienes instalado member color link no deberías tener problemas

The theme is not designed for a 3rd level of submenu, I'll see what can I do

I'm not sure about that error, will have to take a look

Edita el Display del theme default

De momento eso no es compatible
