dhellinger Hi
You can kindly refer to this documentation for creating new module position - besides-login for assigning specific module. Also, You may require to add some CSS rule-sets in order to position the module properly
The code snippet for adding new position can be added in templates/gk_decor/layouts/default.php file above the below mentioned code :
<!-- #gkUser -->
like this
<?php if($this->API->modules('besides-login')) : ?>
<div id="gkUser">
<jdoc:include type="modules" name="besides-login" style="raw" />
</div>
<?php endif; ?>
Hope this helps 🙂
