我在互联网上搜索过,甚至在这个网站上搜索过答案,但没有成功。我遇到的问题是两个下拉按钮登录和注册在单击时显示两个下拉菜单我使用 btn-group 类来解决这个问题但是问题出现了它在较小的移动屏幕上无法正确显示更改它到 btn 类修复了一点然后问题是选项水平显示而不是堆叠看起来很糟糕。我也尝试过 data-target 但这不起作用,我们将不胜感激。这是我的 html 和 css 代码示例。

代码

.navbar {
background-color: #00CED1;
border: none;
}

.navbar-default .navbar-brand {
color: white;
font-family: Tahoma;
font-size: 20px;
font-style: italic;
}

.navbar-left {
width: 70%;
margin-left: -15px;
}

#navForm {
border: none;
}

#loginbtn {
margin-right: 16px;
background: none;
color: white;
border: 2px solid white;
}

#searchbtn {
margin-left: -13px;
background-color: #00b3b3;
color: white;
border-color: #00b3b3;
}

#submitbtn {
width: 100%;
}

#burgerbtn:hover {
background-color: #1673b1;
}

#searchbtn:hover {
background-color: #1673b1;
border-color: #1673b1;
}

#search {
width: 100%;
background-color: #00b3b3;
border: none;
color: white;
}

#password,
#username {
margin-top: 15px;
}

b,
strong {
color: #1673b1;
}

#form {
border: none;
}

#navdiv {
border: none;
}

#form2 input::placeholder {
color: white;
}

#form input::placeholder {
color: white;
}

.navbar-default .navbar-toggle .icon-bar {
background-color: white;
}

.dropdown-menu {
padding-left: 15px;
padding-right: 15px;
}

@media screen and (max-width: 720px) {
b,
strong {
position: absolute;
top: 0.5%;
left: 35%;
}
#navdiv {
width: 80%;
}
.navbar-toggle {
border: none;
}
#navdiv {
width: 165%;
}
.navbar-left {
width: 100%;
}
#loginbtn {
margin-left: 5%;
}
}

#navdiv1 {
border: 1px solid black;
}
