Answer 1

它在Devil的引导线上（第666行）：

.navbar .nav>li>.dropdown-menu:before {
    content: '';
    display: inline-block;
    border-left: 7px solid rgba(0, 0, 0, 0);
    border-right: 7px solid rgba(0, 0, 0, 0);
    border-bottom: 7px solid #CCC;
    border-bottom-color: rgba(0, 0, 0, 0.2);
    position: absolute;
    top: -7px;
    left: 9px;
}

将其删除，或在自定义CSS中覆盖它。

正如Danko指出的那样，还有:after可能导致这种情况。它在（667）之后就行了：

.navbar .nav>li>.dropdown-menu:after {
    content: '';
    display: inline-block;
    border-left: 6px solid rgba(0, 0, 0, 0);
    border-right: 6px solid rgba(0, 0, 0, 0);
    border-bottom: 6px solid #FFF;
    position: absolute;
    top: -6px;
    left: 10px;
}

我的下拉菜单上会出现一个小箭头
