In case of the content display (Intro layout) you would use:
1) Open 'Form&Content type'
2) In Intro, choose option #2 (Link+Markup (Class))
3) There for the field 'Article title' select Content>View
4) Place the 'Article title' field in #TOPBODY position
5) In your seblod template folder /templates/seb_one/positions create a folder *content_alias*/intro (where you substitute the *content_alias* with the real content alias)
6) in this folder, create a topbody.php file with the content
<?php
defined ( '_JEXEC' ) or die;
?>
<a data-lightbox="on" href="/<?php echo $cck->getLink('art_title') ?>"><?php echo $cck->getValue('art_title') ?></a>
Essentially, that should be it. If you select the Disable List Template for List layout, your content Intro layout will be used for displaying search results/lists.
P.S. Remove the forward slash / behind href=
