Bootstrap導航欄未對齊下拉菜單

Question

我有一個導航欄有幾個下拉菜單。它們已被修改，以使用一個容器，以顯示下拉內容4列

注意，用於在導航欄每個下拉菜單中，在下拉菜單中沒有與所述容器（灰色區域）神韻：。我希望將所有下拉列表與容器對齊。

我試過絕對定位這個，但它不工作得很好，我想知道是否有更好的引導方式做到這一點？

代碼：

Answer 1

您的每一個dropdown-menu包含<div class="container">已經固定width對應的屏幕尺寸。

你應該手動設置容器寬度：

@media (min-width: 768px) { 
    .custom-width { 
    width: ... !important; 
    } 
} 
@media (min-width: 992px) { 
    .custom-width { 
    width: ... !important; 
    } 
} 
@media (min-width: 1200px) { 
    .custom-width { 
    width: ... !important; 
    } 
}
