Dropdown menu does not expand - Bootstrap-CodePudding

I am trying to setup a hamburger menu using bootstrap. I went through my code, added in the css and js files, and the menu does not work i.e. it does not expand. I have used the example code from the bootstrap website. Any help would be appreciated to resolve this.

HTML:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>IDS PANEL CONFIG</title>

  <body>
    <div >
        <div  id="navbarToggleExternalContent">
          <div >
            <h5 >Collapsed content</h5>
            <span >Toggleable via the navbar brand.</span>
          </div>
        </div>
        <nav >
          <button  type="button" data-toggle="collapse" data-target="#navbarToggleExternalContent" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
            <span ></span>
          </button>
        </nav>
        <div>
            <h1 style="font-size:50px;">CONFIG</h1>
            <p style="font-size:50px;color: crimson;">Zone report</p>
          <p><strong> please wait...</strong></p>
        </div>
    </div>
<div class = "container"></div>

You are using Bootstrap version 5 but your code is for version 4.
If you change data-toggle to data-bs-toggle and data-target to data-bs-target it should work.
