Hi!
Thanks for taking the time to reach out to us. To clarify you were hoping to get the wpshindig navigation “Calendar”, “Add Your Event”, … style when you purchased Events Calendar PRO, is that correct?
I’m sorry but the navigation is part of the theme styling and isn’t part of the calendar or add-on plugins. If you want to ave a similar navigation for your site you could inspect the wpshindig’s css and see how to setup a similar look and feel or you could go to the wordpress.org theme directory and find similar themes to base your site off of.
Hope this information answers your question.
