To start with there is no need for a specialist plugin, though you may want to consider a filtering option on your site later.

Documentation in Portuguese on how to set up categories is available here:

And on display of category pages here:

Filtering widgets are included and documentation can be found here:

We’ve not heard back from you in a while, so I’m marking this thread as resolved. Hopefully, the above info was helpful!

If you have further questions, please feel free to open a new topic.

Thanks.
