CSS でドロップダウン メニューを作成しましたが、奇妙なことにすべてのドロップダウン メニューが左揃えになっています。すべてのドロップダウンが表示され、親メニューの下にドロップされることを願っています。
HTML は次のとおりです。
<div id="menu">
<ul>
<li ng-class="{selected: $index==currPage}" ng-repeat="page in data.pages" class="ng-scope selected">
<a href="" ng-click="goToPage($index)" class="ng-binding">Introduction</a>
<ul>
<!-- ngRepeat: smenu in data.subMenu[$index].list --><li ng-class="{$index==currMenu}" ng-repeat="smenu in data.subMenu[$index].list" class="ng-scope">
<a href="" ng-click="goToPage($index)" class="ng-binding">Profile</a>
</li><li ng-class="{$index==currMenu}" ng-repeat="smenu in data.subMenu[$index].list" class="ng-scope">
<a href="" ng-click="goToPage($index)" class="ng-binding">Background</a>
</li><li ng-class="{$index==currMenu}" ng-repeat="smenu in data.subMenu[$index].list" class="ng-scope">
<a href="" ng-click="goToPage($index)" class="ng-binding">What is KAM</a>
</li>
</ul>
</li>
...
</div>
以下はCSSです: -
#menu {
/*border-bottom:4px seagreen solid;*/
background-color: #2d394d;
list-style:none;
}
#menu ul {
list-style: none;
}
#menu ul li {
display: inline-block;
float: none;
/*width: 20%;*/
}
#menu ul li a{
font-size: 10pt;
padding:12px 24px 12px 24px;
/*border-right:1px white solid;*/
display:block;
text-decoration: none;
text-align: center;
color:#fff;
text-transform: uppercase;
}
#menu ul li a:hover{
}
#menu ul li.selected a {
background-color: #1b86c2;
color:#fff;
}
/* DropDown Menus */
#menu ul ul{
background:#fff; /* Adding a background makes the dropdown work properly in IE7+. Make this as close to your page's background as possible (i.e. white page == white background). */
background:rgba(255,255,255,0); /* But! Let's make the background fully transparent where we can, we don't actually want to see it if we can help it... */
list-style:none;
position:absolute;
left:-9999px; /* Hide off-screen when not needed (this is more accessible than display:none;) */
}
#menu ul li ul li{
padding-top:1px; /* Introducing a padding between the li and the a give the illusion spaced items */
float:none;
display: block;
}
#nav ul ul a{
white-space:nowrap; /* Stop text wrapping and creating multi-line dropdown items */
}
#menu li:hover ul{ /* Display the dropdown on hover */
left:0; /* Bring back on-screen when needed */
}
#menu li:hover a{ /* These create persistent hover states, meaning the top-most link stays 'hovered' even when your cursor has moved down the list. */
background:#1b86c2;
text-decoration:underline;
}
#menu li:hover ul a{ /* The persistent hover state does however create a global style for links even before they're hovered. Here we undo these effects. */
text-decoration:none;
}
#menu li:hover ul li a:hover{ /* Here we define the most explicit hover states--what happens when you hover each individual link. */
background:#333;
}
ここでそれを示す画像を見ることができます (画像は「ケース」のドロップダウンを示しています。ケースの下にあるはずですが、左にシフトされています。「紹介」サブメニューも同じ場所に表示されます):-
