AshleshaJS is a framework to build high performance and maintainable single page web applications. It uses ExpressJS and YUI3 as foundation. It is tightly coupled with Twitter Bootstrap for the CSS framework but you can use any other framework as well.

// DROPDOWN MENUS
// --------------

// Use the .menu class on any <li> element within the topbar or ul.tabs and you'll get some superfancy dropdowns
.dropup,
.dropdown {
  position: relative;
}
.dropdown-toggle {
  // The caret makes the toggle a bit too tall in IE7
  *margin-bottom: -3px;
}
.dropdown-toggle:active,
.open .dropdown-toggle {
  outline: 0;
}

// Dropdown arrow/caret
// --------------------
.caret {
  display: inline-block;
  width: 0;
  height: 0;
  vertical-align: top;
  border-top:   4px solid @black;
  border-right: 4px solid transparent;
  border-left:  4px solid transparent;
  content: "";
  .opacity(30);
}

// Place the caret
.dropdown .caret {
  margin-top: 8px;
  margin-left: 2px;
}
.dropdown:hover .caret,
.open .caret {
  .opacity(100);
}

// The dropdown menu (ul)
// ----------------------
.dropdown-menu {
  position: absolute;
  top: 100%;
  left: 0;
  z-index: @zindexDropdown;
  display: none; // none by default, but block on "open" of the menu
  float: left;
  min-width: 160px;
  padding: 4px 0;
  margin: 1px 0 0; // override default ul
  list-style: none;
  background-color: @dropdownBackground;
  border: 1px solid #ccc;
  border: 1px solid rgba(0,0,0,.2);
  *border-right-width: 2px;
  *border-bottom-width: 2px;
  .border-radius(5px);
  .box-shadow(0 5px 10px rgba(0,0,0,.2));
  -webkit-background-clip: padding-box;
     -moz-background-clip: padding;
          background-clip: padding-box;

  // Aligns the dropdown menu to right
  &.pull-right {
    right: 0;
    left: auto;
  }

  // Dividers (basically an hr) within the dropdown
  .divider {
    .nav-divider(@dropdownDividerTop, @dropdownDividerBottom);
  }

  // Links within the dropdown menu
  a {
    display: block;
    padding: 3px 15px;
    clear: both;
    font-weight: normal;
    line-height: @baseLineHeight;
    color: @dropdownLinkColor;
    white-space: nowrap;
  }
}

// Hover state
// -----------
.dropdown-menu li > a:hover,
.dropdown-menu .active > a,
.dropdown-menu .active > a:hover {
  color: @dropdownLinkColorHover;
  text-decoration: none;
  background-color: @dropdownLinkBackgroundHover;
}

// Open state for the dropdown
// ---------------------------
.open {
  // IE7's z-index only goes to the nearest positioned ancestor, which would
  // make the menu appear below buttons that appeared later on the page
  *z-index: @zindexDropdown;

  & > .dropdown-menu {
    display: block;
  }
}

// Right aligned dropdowns
// ---------------------------
.pull-right > .dropdown-menu {
  right: 0;
  left: auto;
}

// Allow for dropdowns to go bottom up (aka, dropup-menu)
// ------------------------------------------------------
// Just add .dropup after the standard .dropdown class and you're set, bro.
// TODO: abstract this so that the navbar fixed styles are not placed here?
.dropup,
.navbar-fixed-bottom .dropdown {
  // Reverse the caret
  .caret {
    border-top: 0;
    border-bottom: 4px solid @black;
    content: "\2191";
  }
  // Different positioning for bottom up menu
  .dropdown-menu {
    top: auto;
    bottom: 100%;
    margin-bottom: 1px;
  }
}

// Typeahead
// ---------
.typeahead {
  margin-top: 2px; // give it some space to breathe
  .border-radius(4px);
}
