Hello, I have been dabbling with this for awhile and would like to seek the community's help.
In the Bootstrap v5.3 navbar dropdown implementation, the dropdown doesn't display when viewed on a full-sized window. However, when the window size is reduced (to the extent the navbar collapses), the dropdown can actually be displayed.
Would appreciate if I could get some advice on this problem.

Here's my code.

<head>

  <title>SpendSmart</title>

  <link rel="stylesheet" href="A1.css">
</head>

<body onload="main();">
  <h1>SpendSmart</h1>

  <nav class="navbar navbar-expand-lg bg-body-tertiary">
    <div class="container-fluid">
      <a class="navbar-brand" href="#">Navbar</a>

        <span class="navbar-toggler-icon"></span>
      </button>
      <div class="collapse navbar-collapse" id="navbarNavDropdown">
        <ul class="navbar-nav">

I've created this CodePen with your code. Looks like the "Dropdown link" is well-rendered in the navbar and is actionable (menu is displayed) both in desktop or mobile modes. Am I missing something?
