Hi there, Emily! Thanks for getting in touch. 🙂
The best way to show past events with upcoming events is to create a theme override of the template you are using and create a custom query using the tribe_get_events() function. The function works a lot like the WordPress get_posts() function, so you could use something like this:
<?php
global $post;
$all_events = tribe_get_events(array(
'eventDisplay' => 'all',
'posts_per_page' => 10,
)); ?>
Naturally, you would want to customize this to fit your needs and layout.
Another option is to use add a filter to your theme’s functions.php file that adds past events to your list of upcoming events. That solution is outlined in this thread.
It’s a bit of customization, but I hope this points you in the right direction.
Cheers!
Geoff
