Navbar not collapsing in asp.NET webform

Question

I'm doing an ASP.NET web page which includes a navbar using bootstrap 4. When the screen is small I got the toggle button to appear, but when I click it nothing happens, it looks like it tries to show the menu options, but nothing happens. The navber is inside the form tag, everything works fine if I put the navbar outside the form tag.

Can anyone tell me what's happening here, I have no clue now, thanks

I think you're missing to link your JavaScript libaries correctly at the top. Please check this.

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Navbar</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-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 mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
      <li class="nav-item dropdown">
        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
          Dropdown
        </a>
        <div class="dropdown-menu" aria-labelledby="navbarDropdown">
          <a class="dropdown-item" href="#">Action</a>
          <a class="dropdown-item" href="#">Another action</a>
          <div class="dropdown-divider"></div>
          <a class="dropdown-item" href="#">Something else here</a>
        </div>
      </li>
      <li class="nav-item">
        <a class="nav-link disabled" href="#">Disabled</a>
      </li>
    </ul>
    <form class="form-inline my-2 my-lg-0">
      <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
      <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
    </form>
  </div>
</nav>

thanks but still not working, it works fine when it's just html but when I out the navbar code inside

the toggle functionality stops working — David Reyes, Oct 21 '19 at 20:55
yes, because
is letting toggler to hyperlink to OnPost route, which is overriding the default id link which to open the menu when screen is small. — muhammad tayyab, Oct 21 '19 at 23:54
I think by using "runat=Server" attribute you are changing stylesheet path. I just heard from this answer. The one answer by @xypho https://stackoverflow.com/questions/11510502/understanding-the-runat-server-attribute — muhammad tayyab, Oct 24 '19 at 01:00
