Include an external HTML fragment angularjs

Create new file you want to include with some content, for example bootstrap navbar: ‘navbar.html’

 <nav class="navbar navbar-expand-md navbar-dark bg-dark fixed-top">
 <a class="navbar-brand" href="#">Navbar</a>
 <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
 <div class="collapse navbar-collapse" id="navbarsExampleDefault">
 <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">
 <a class="nav-link disabled" href="#">Disabled</a>
 </li>
 <li class="nav-item dropdown">
 <a class="nav-link dropdown-toggle" href="http://example.com" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown</a>
 <div class="dropdown-menu" aria-labelledby="dropdown01">
 <a class="dropdown-item" href="#">Action</a>
 <a class="dropdown-item" href="#">Another action</a>
 <a class="dropdown-item" href="#">Something else here</a>
 </div>
 </li>
 </ul>
 <form class="form-inline my-2 my-lg-0">
 <input class="form-control mr-sm-2" type="text" placeholder="Search" aria-label="Search">
 <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
 </form>
 </div>
</nav>

Add this code into your index.html

 <ng-include src="'navbar.html'"></ng-include>

NB! If the source is a string constant, make sure you wrap it in single quotes, e.g. src=”‘myPartialTemplate.html'”.
