Need to display Subject (Mail subject) - Vtiger CRM
<p>I need to display Mail subject in Related tab Grid of Lead module</p>

<p><a href="https://i.stack.imgur.com/iFIq0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/iFIq0.png" alt="enter image description here"></a></p>

<p>I have checked <code>getRelationQuery()</code> function in that I got a subject, but while on the <code>EmailRelatedlist.tpl</code> file, the subject data is not displayed.</p>

<p>How we can display the Subject on the Related tab?</p>
