Hi Igor,
Let's just simplify my question, please take a look at the screenshot picture that I sent.
Currently, it shows price comparisons from five vendors.
What if I want to limit it to only 3?
I don't understand your instructions below, can you show me more details, about the menu navigation on how to set it? I have no WordPress experience.
Thanks
unfortunately if you don't understand what I have written I can't advice you to do such customizations, because this can make your site as not operable if you will do wrong change and this requires to change core files. Maybe better to hire someone for this job, you can show my comment to your developer
