Bootstrap Snippet Easy Table Filter

I am using this Snippet
My problem is that I have not figured out how to have one button selected when going to the page so that the user doesn’t have to click on the first button.
EX: My first button is Popular or (Pagado in the Snippet) and I would like for the menu items under Popular (Pagado) to show when going to index.html. At the moment all of the menu items show from all categories / buttons.
