Vertical menu

I would like to have the Vertical menu collapsed by default. (show icon only)

Thank you for your help

Depend on the layout you're using, you can open the respective layout file in: root/templates/ja_intranet/tpls/ directory.

For example, if your your homepage is using dashboard layout, you open the file: root/templates/ja_intranet/tpls/dashboard.php

Look for this line of code:
<div class="t3-wrapper layout-<?php echo $menuPosition; ?>">

change it to:
<div class="t3-wrapper layout-<?php echo $menuPosition; ?> navbar-hidden">
