how to prevent bootstrap navbar split into few lines when collapsed - css

Question

I've been searching for it all day and couldn't find a solution, so I hope I won't look like an idiot when in 2 minutes someone will post an answered link for the exact question.
I am trying to create a navbar like on steamdb
Where the search box remains after the navbar collapse and is just reduced in size.
But I ran into the problem where if I set the navbar to <nav class="navbar-expand-lg" </nav> then when it collapses it split into 3 lines, one for the brand, one for search, and one for toggle dropdown.
If I remove the "-lg" then it doesn't split, but then it also doesn't change the items to toggle.
<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 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">test2</a></li>
<li><a class="dropdown-item" href="/test3">test3</a></li>
</ul>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Donate</a>
</li>
</ul>
</div>
</div>
</nav>

Please help, I've been stuck on this all day

You need to use 2 inner divs inside the container. Make them both w-100, and the first one d-flex so that the brand and form layout horizontally...
<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>
</ul>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Donate</a>
</li>
</ul>
</div>
</div>
</nav>
