title: How to Fix this error in Angular Application "No provider for ControlContainerAngular"
body: <p>I am using bootstrap-4 in my angular7 application. I want to design my application with bootstrap</p>
  <pre><code> &lt;nav class=&quot;navbar navbar-light bg-light&quot;&gt;
    &lt;form class=&quot;form-inline&quot;&gt;
      &lt;div class=&quot;input-group&quot;&gt;
        &lt;div class=&quot;input-group-prepend&quot;&gt;
          &lt;span class=&quot;input-group-text&quot; id=&quot;basic-addon1&quot;&gt;@&lt;/span&gt;
        &lt;/div&gt;
        &lt;input type=&quot;text&quot; class=&quot;form-control&quot; placeholder=&quot;Username&quot; aria-label=&quot;Username&quot; aria-describedby=&quot;basic-addon1&quot;&gt;
      &lt;/div&gt;
    &lt;/form&gt;
  &lt;/nav&gt;
  </code></pre>
  <p>I expected that there should be  search box as including in bootstrap documentation but the error is  &quot;No provider for ControlContainer Angular&quot;</p>
