Portfolio → Settings holds the options that apply to your whole portfolio: URL slugs, the design of category archive pages, and (with PRO) video-player preferences and extra post types.

Table of Contents
project → https://yoursite.com/project/my-work/.portfolio → https://yoursite.com/portfolio/branding/.Two rules to avoid broken pages:
/portfolio/ clashes with the default taxonomy slug — rename one of them).On WPZOOM themes with a built-in portfolio (Inspiro family), the theme controls these permalinks — the fields here are read-only and the same options live in the Theme Options panel.
Custom Post Types lists your site’s other post types; ticking one makes it selectable as a source in the Portfolio block’s Post Type dropdown — display products, team members or any CPT in the portfolio grid design.
Each portfolio category gets its own archive page (e.g. /portfolio/branding/). This tab styles those pages when “Use the template provided by the plugin” is enabled:
Turn the template off if your theme ships its own portfolio archive design (themes can also override it by providing a taxonomy-portfolio.php file).
