Hi Erik,

I hope you are well today and thank you for your question.

You can achieve it by adding the following CSS code in the Custom CSS code option of your theme on the below path.

Admin Area -> Appearance -> Theme Settings -> Custom Code -> CSS Code

.page-id-90 .sh-portfolio-filter-style2 {
    display: none;
}

Best regards,

Out of curiosity, is it pretty easy to remove the category selector, but display a particular category (rather than all categories)?

If you tell me which particular category you want to display on your site then i can develop custom CSS code to achieve this.

I tried to access your shared portfolio page to develop custom CSS code to show the category “Books” but the page is not accessible.

Could you please make sure that the page is accessible and working?

To achieve this please try using the custom plugin solution shared in the following topic.
