Good evening Raj and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
I would love to help you with this topic.
When a specific event is clicked there should be different packages available for them.
On the website example you have provided, the different packages are actually images that links to another page.
The great news is that even with our free the Events Calendar plugin, you will be able insert images and text to your specifications, including links to other pages.
To reproduce this you will need:
- the Events Calendar free
- WooCommerce
Simply create WooCommerce Products that reflect your packages (simple or variable virtual products) and then include them via embed or links in images in your events.
Let me know if that helps.
Have a great day!
Geoff B.
