Hello Sviat,
Thanks for checking out our plugins!
Event Tickets Plus integrates with either WooCommerce or Easy Digital Downloads to sell tickets, so depending on which platform you go with, tickets will be created as products within that platform. However, you can create tickets on many different post types, including pages. I am not very familiar with the Elementor plugin, but I would recommend creating tickets on pages that do work with the page builder. In this case, the tickets should be added to the bottom of the content that you created with the builder.
You would really need to test this out to make sure that you can get it working the way you need. We do offer full refunds within 30 days of purchase, so if you’d like to take Event Tickets Plus for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
