Are you wondering how to do this from a list view?
If it's from a list view, then you can do an override of one of the custom views. For example, copy:
public_html/components/com_contentbuilder/views/list/tmpl/default.php
to:
/templates/{your_template}/html/com_contentbuilder/list/** You'll have to create the folders **
Then rename default.php you just copied into your templates folder to "listone.php"
Then in your menuitem, make sure you point your list to Custom List 1.
now you can modify this listone.php inside your templates folder without touching the original!
Add this at the very top of your templates index.php file.
<?php JHTML::_('behavior.modal'); ?>
Then inside listone.php find line: 518. You should see:
<a href="<?php echo $link; ?>"><?php echo $value; ?></a>
and change it to:
<a href="<?php echo $link; ?>" class="modal"><?php echo $value; ?></a>
Go ahead and try that and see what happens? Untested... but thinking this should work.
