如何將搜索表單放在導航欄中間并在Bootstrap5中展開它

我正在使用 Bootstrap v5.1.3 并且我添加了一個這樣的導航欄：

導航欄

這是代碼：

        <div class="container">
            <nav class="navbar navbar-expand-lg navbar-light bg-light">
                <div class="container-fluid">
                    <a class="navbar-brand" href="#">Navbar</a>
                    <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">
                        <form class="d-flex">
                            <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
                            <button class="btn btn-outline-success" type="submit">Search</button>
                        </form>
                        <ul class="navbar-nav ms-auto mb-2 mb-lg-0">
                            <li class="nav-item dropdown">
                                <a class="nav-link dropdown-toggle" id="navbarDropdown" href="#" role="button" data-bs-toggle="dropdown" aria-expanded="false">Cart</a>
                                <ul class="dropdown-menu dropdown-menu-end" aria-labelledby="navbarDropdown">
                                    <li><a class="dropdown-item" href="#">Action</a></li>
                                    <li><a class="dropdown-item" href="#">Another action</a></li>
                                    <li><hr class="dropdown-divider" /></li>
                                    <li><a class="dropdown-item" href="#">Something else here</a></li>
                                </ul>
                            </li>
                        </ul>
                    </div>
                </div>
            </nav>
        </div>

但是我需要擴展搜索表單并將其放置在導航欄的中心，所以它看起來像這樣：

預期的搜索表單示例

所以我嘗試在表單中添加 id ：

<form class="d-flex" id="search">

并補充說：

#search{
   text-align:center;
}

但它仍然無法解決并在左側顯示搜索表單。

那么如何將這個搜索表單放在導航欄的中間，并在 Bootstrap 5 中稍微擴展它呢？

使用flex-grow-1使其擴大...
