[web2py] Re: Anyone using BootSwatch with new web2py layout

[Niphlod]

I may be a little late....I implemented it for my app but never used 
because my menu has only 4 items :-P
include bootstrap.css and add to css this (took from 
https://github.com/twitter/bootstrap/issues/424)

.nav li.dropdown ul.dropdown-menu li:HOVER ul {
        display:block;
        position:absolute;
        left:100%;
        -webkit-border-radius: 3px;
        -moz-border-radius: 3px;
        border-radius: 3px;
    }
    .nav li.dropdown ul.dropdown-menu ul {
        display: none;
        float:right;
        position: relative;
        top: auto;
        margin-top: -30px;
    }

    .nav li.dropdown ul.dropdown-menu .dropdown-menu::before {
        content: '';
        display: inline-block;
        border-top: 7px solid transparent;
        border-bottom: 7px solid transparent;
        border-right:7px solid #CCC;
        border-right-color: rgba(0, 0, 0, 0.2);
        position: absolute;
        top: 9px;
        left: -14px;
    }

    .nav li.dropdown ul.dropdown-menu .dropdown-menu::after {
        content: '';
        display: inline-block;
        border-top: 6px solid transparent;
        border-bottom: 6px solid transparent;
        border-right:6px solid white;
        position: absolute;
        top: 10px;
        left: -12px;
    }


def twitter_menu(menu, level=0):
    """
    Generates twitter bootstrap's compliant menu
    """
    lis = []
    for li in menu:
        (text, active, href) = li[:3]
        sub =  len(li) > 3 and li[3] or []
        if len(sub) == 0:
            li_class = None
            el = LI(A(text, _href=href), _class=li_class)
        else:
            li_class = 'dropdown'
            caret = level == 0 and B(_class='caret') or 
I(_class='icon-chevron-right')
            sub_ul = twitter_menu(sub, level=level+1)
            el = LI(A(text, caret, _href=href, _class="dropdown-toggle", 
**{'_data-toggle' : 'dropdown'}), sub_ul, _class=li_class)
        lis.append(el)

    if level == 0:
        return UL(*lis, _class='nav')
    else:
        return UL(*lis, _class="dropdown-menu")
