Hello,
Thanks for reaching out!
I would first try setting theĀ “Events template” setting under Events > Settings > Display to “Default Page Template”? If your theme’s default page template includes the sidebar that you want to add to the events pages, then this should work.
If not, you can do a template override of the default-template.php file and add the sidebar in there – the WordPress documentation on adding sidebars for some code examples.
We are limited in the amount of support that we can provide for customizations, but if you get stuck or have any questions, please let me know – I’ll be happy to try to point you in the right direction!
Thanks,
Jennifer
