我已经搜索了一整天，没有找到一个解决方案，所以我希望我不会看起来像一个白痴时，在2分钟内有人将一个回答的链接，为确切的问题。
我正在尝试创建一个像在steamdb上那样的navbar，在navbar折叠后搜索框仍然保留，并且只是减小了尺寸。
但是我遇到了一个问题，如果我将navbar设置为
如果我移除“-lg”，那么它就不会分裂，但是它也不会改变要切换的项目。
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container">
<a class="navbar-brand" href="/">My Company Name</a>
<form class="d-flex w-100 d-inline-block">
<div class="input-group">
<input class="form-control no-border" type="text" placeholder="search for game..." id="example-search-input">
<span class="input-group-append">
<button class="btn rounded-pill" type="button">
<i class="bi bi-search"></i>
</button>
</span>
</div>
</form>
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent"
aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<ul class="navbar-nav ms-auto mb-2 mb-lg-0">

</li>
<li class="nav-item dropdown">

aria-expanded="false">

请帮帮我，我一整天都困在这件事上了
您需要在容器内部使用2个内部div。使他们都W-100，和第一个D-flex，以便品牌和形式布局水平...
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container">
<div class="d-flex w-100">
<a class="navbar-brand" href="/">My Company Name</a>
<form class="d-flex w-100 d-inline-block">
<div class="input-group">
<input class="form-control no-border" type="text" placeholder="search for game..." id="example-search-input">
<span class="input-group-append">
<button class="btn rounded-pill" type="button">
<i class="bi bi-search"></i>
</button>
</span>
</div>
</form>
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
</div>
<div class="collapse navbar-collapse w-100" id="navbarSupportedContent">
<ul class="navbar-nav ms-auto mb-2 mb-lg-0">
<li class="nav-item">
<a class="nav-link active" aria-current="page" href="/">Home</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-bs-toggle="dropdown" aria-expanded="false"> content </a>
<ul class="dropdown-menu" aria-labelledby="navbarDropdown">
<li><a class="dropdown-item" href="/test1">test1</a></li>
<li><a class="dropdown-item" href="/test2">something</a></li>
<li><a class="dropdown-item" href="/test3">bla bla</a></li>
