HTML/CSS功能區列表

Question

我在我的網站（首頁，關於，故事）的主頁上創建了一個功能區，僅使用HTML和CSS的水平線。 「故事」按鈕顯示兩個項目的下拉菜單。我的問題是這樣的：我怎樣才能使用類似的方法，以便在從主功能區下拉的某個選項旁邊出現放置「右鍵」菜單？我已經包含了下面的圖片和代碼。我意識到這可能是非常複雜的;我是初學者。

代碼（HTML）：

<div id="animatedRibbon"> 
    <nav> 
     <ul> 
      <li class="sub-menu-parent"><a href="#">Home</a></li> 
      <li class="sub-menu-parent"><a href="#">Story</a> 
       <ul class="sub-menu"> 
        <li><a href="#" class="sub-sub-menu-parent2015">2015</a> 
         <ul class="sub-sub-menu2015"> 
          <li class="option2015"><a href="#">March</a></li> 
          <li class="option2015"><a href="#">April</a></li> 
          <li class="option2015"><a href="#">May</a></li> 
          <li class="option2015"><a href="#">June</a></li> 
          <li class="option2015"><a href="#">July</a></li> 
          <li class="option2015"><a href="#">August</a></li> 
          <li class="option2015"><a href="#">September</a>    </li> 
          <li class="option2015"><a href="#">October</a></li> 
          <li class="option2015"><a href="#">November</a></li> 
          <li class="option2015"><a href="#">December</a></li> 
         </ul> 
        </li> 
        <li><a href="#" class="sub-sub-menu-parent-2016">2016</a> 
         <ul class="sub-sub-menu2016"> 
          <li class="option2016"><a href="#">January</a></li> 
          <li class="option2016"><a href="#">February</a></li> 
          <li class="option2016"><a href="#">March</a></li> 
          <li class="option2016"><a href="#">April</a></li> 
          <li class="option2016"><a href="#">May</a></li> 
          <li class="option2016"><a href="#">June</a></li> 
          <li class="option2016"><a href="#">July</a></li> 
          <li class="option2016"><a href="#">August</a></li> 
          <li class="option2016"><a href="#">September</a></li> 
          <li class="option2016"><a href="#">October</a></li> 
          <li class="option2016"><a href="#">November</a></li> 
          <li class="option2016"><a href="#">December</a></li> 
         </ul> 
        </li> 
       </ul> 
      </li> 
      <li class="sub-menu-parent"><a href="about.html">About</a></li> 
     </ul> 
    </nav> 
</div> 

CSS：

.sub-menu-parent { position: relative; } 

.sub-menu { 
    visibility: hidden; /* hides sub-menu */ 
    opacity: 0; 
    position: absolute; 
    top: 100%; 
    left: 0%; 
    width: 100%; 
    transform: translateY(-1em); 
    z-index: 0; 
    transition: all 0.3s ease-in-out 0s, visibility 0s linear 0.3s, z-index 0s linear 0.01s;} 

.sub-menu-parent:hover .sub-menu { 
    visibility: visible; /* shows sub-menu */ 
    opacity: 0.85; 
    z-index: 1; 
    transform: translateY(0%); 
    transition-delay: 0s, 0s, 0.3s; /* this removes the transition delay so the menu will be visible while the other styles transition */} 


.sub-sub-menu2015 { 
    visibility: hidden; 
    opacity: 1; 
    position: absolute; 
    top: 0%; 
    left: 50%;

/*body { padding: 2%; font: 18px/1.4 sans-serif; }*/ 

nav a { color: #E00; display: block; padding: 0.5em 1em; text-decoration: none;} 
nav a:hover { color: #F55; } 
nav ul, 
nav ul li { list-style-type: none; padding: 0; margin: 0; } 

nav > ul { background: #ffdead; text-align: center; } 
nav > ul > li { display: inline-block; border-left: solid 1px #aaa; } 
nav > ul > li:first-child { border-left: none; } 

.sub-menu { 
    background: #ffdead;} 

nav > ul > li > a:link { 
    font-size: 36px;} 

nav > ul > li > a:hover,

下面是一些圖像細節正是我想說的。 Main menu ribbon with drop down menu Desired effect (1)

在CSS的微小變化會給你你想爲你的sub-sub-menus預期的效果。

這裏的CSS：

ul[class*="sub-sub-menu"] { 
    background: #ffdead; 
    left: 100%; 
    top: 0%; 
    transition-delay: 0s, 0s, 0.3s; 
} 

.sub-menu-parent .sub-menu li { 
    position: relative; 
} 

.sub-menu-parent .sub-menu li:hover .sub-sub-menu2015, 
.sub-menu-parent .sub-menu li:hover .sub-sub-menu2016 { 
    visibility: visible; 
    opacity: 0.85; 
    z-index: 1; 
    transform: translateY(0%); 
}
