show input field once drop down is selected in Contact Form 7
<p>Hi guys I am using Wordpress Contact Form 7 plugin and trying to achieve: <strong>Show text field if drop down "Other" is selected</strong></p>

<p><a href="https://i.stack.imgur.com/bZqTB.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bZqTB.jpg" alt="Drop down menu items"></a></p>

<p>I am using following raw JS for now through Visual composer in Wordpress Page after adding <code>dropdown</code> as id in Contact Form 7:</p>

<pre><code>var x = document.getElementById("dropdown");
if(x.value = "Other") {
 alert('Enter your js here!');
}
</code></pre>
