Hi Annie,
Thanks for using our plugins. I can help out here.
We do not have a feature to collapse the list view description.
However, you could edit the template following our themer’s guide:
https://theeventscalendar.com/knowledgebase/themers-guide/
Following that guide you can move and edit this file in your theme:
the-events-calendar\src\views\list\single-event.php
You could then remove this from that template and the description would not display in list view only:
<div class="tribe-events-list-event-description tribe-events-content description entry-summary">
<?php the_excerpt() ?>
" class="tribe-events-read-more" rel="bookmark"><?php _e( 'Find out more', 'tribe-events-calendar' ) ?> »
</div><!-- .tribe-events-list-event-description -->
Let me know how that works out.
Thanks
