本章將重點介紹 Bootstrap 下拉菜單。下拉菜單是可切換的,是以列表格式顯示鏈接的上下文菜單。這可以通過與 下拉菜單(Dropdown) JavaScript 插件 的互動來實現(xiàn)。
如需使用下列菜單,只需要在 class .dropdown 內(nèi)加上下拉菜單即可。下面的實例演示了基本的下拉菜單:
<!DOCTYPE?html> <html> <head> ???<title>Bootstrap?實例?-?下拉菜單(Dropdowns)</title> ???<link?href="/bootstrap/css/bootstrap.min.css"?rel="stylesheet"> ???<script?src="/scripts/jquery.min.js"></script> ???<script?src="/bootstrap/js/bootstrap.min.js"></script> </head> <body> <div?class="dropdown"> ???<button?type="button"?class="btn?dropdown-toggle"?id="dropdownMenu1"? ??????data-toggle="dropdown"> ??????主題 ??????<span?class="caret"></span> ???</button> ???<ul?class="dropdown-menu"?role="menu"?aria-labelledby="dropdownMenu1"> ??????<li?role="presentation"> ?????????<a?role="menuitem"?tabindex="-1"?href="#">Java</a> ??????</li> ??????<li?role="presentation"> ?????????<a?role="menuitem"?tabindex="-1"?href="#">數(shù)據(jù)挖掘</a> ??????</li> ??????<li?role="presentation"> ?????????<a?role="menuitem"?tabindex="-1"?href="#"> ????????????數(shù)據(jù)通信/網(wǎng)絡(luò) ?????????</a> ??????</li> ??????<li?role="presentation"?class="divider"></li> ??????<li?role="presentation"> ?????????<a?role="menuitem"?tabindex="-1"?href="#">分離的鏈接</a> ??????</li> ???</ul> </div> </body> </html>
結(jié)果如下所示:
通過向 .dropdown-menu 添加 class .pull-right 來向右對齊下拉菜單。下面的實例演示了這點:
<!DOCTYPE?html> <html> <head> ???<title>Bootstrap?實例?-?向右對齊下拉菜單</title> ???<link?href="/bootstrap/css/bootstrap.min.css"?rel="stylesheet"> ???<script?src="/scripts/jquery.min.js"></script> ???<script?src="/bootstrap/js/bootstrap.min.js"></script> </head> <body> <div?class="dropdown"> ???<button?type="button"?class="btn?dropdown-toggle"?id="dropdownMenu1"? ??????data-toggle="dropdown">主題 ??????<span?class="caret"></span> ???</button> ???<ul?class="dropdown-menu?pull-right"?role="menu"? ??????aria-labelledby="dropdownMenu1"> ??????<li?role="presentation"> ?????????<a?role="menuitem"?tabindex="-1"?href="#">Java</a> ??????</li> ??????<li?role="presentation"> ?????????<a?role="menuitem"?tabindex="-1"?href="#">數(shù)據(jù)挖掘</a> ??????</li> ??????<li?role="presentation"> ?????????<a?role="menuitem"?tabindex="-1"?href="#"> ????????????數(shù)據(jù)通信/網(wǎng)絡(luò) ?????????</a> ??????</li> ??????<li?role="presentation"?class="divider"></li> ??????<li?role="presentation"> ?????????<a?role="menuitem"?tabindex="-1"?href="#">分離的鏈接</a> ??????</li> ???</ul> </div> </body> </html>
結(jié)果如下所示:
您可以使用 class dropdown-header 向下拉菜單的標簽區(qū)域添加標題。下面的實例演示了這點:
<!DOCTYPE?html> <html> <head> ???<title>Bootstrap?實例?-?下拉菜單標題</title> ???<link?href="/bootstrap/css/bootstrap.min.css"?rel="stylesheet"> ???<script?src="/scripts/jquery.min.js"></script> ???<script?src="/bootstrap/js/bootstrap.min.js"></script> </head> <body> <div?class="dropdown"> ???<button?type="button"?class="btn?dropdown-toggle"?id="dropdownMenu1"? ??????data-toggle="dropdown"> ??????主題 ??????<span?class="caret"></span> ???</button> ???<ul?class="dropdown-menu"?role="menu"?aria-labelledby="dropdownMenu1"> ??????<li?role="presentation"?class="dropdown-header">下拉菜單標題</li> ??????<li?role="presentation"?> ?????????<a?role="menuitem"?tabindex="-1"?href="#">Java</a> ??????</li> ??????<li?role="presentation"> ?????????<a?role="menuitem"?tabindex="-1"?href="#">數(shù)據(jù)挖掘</a> ??????</li> ??????<li?role="presentation"> ?????????<a?role="menuitem"?tabindex="-1"?href="#"> ????????????數(shù)據(jù)通信/網(wǎng)絡(luò) ?????????</a> ??????</li> ??????<li?role="presentation"?class="divider"></li> ??????<li?role="presentation"?class="dropdown-header">下拉菜單標題</li> ??????<li?role="presentation"> ?????????<a?role="menuitem"?tabindex="-1"?href="#">分離的鏈接</a> ??????</li> ???</ul> </div> </body> </html>
