pom://theme/mergetags/feed: the listing-item catalog

This JSON resource describes the widest of the three POM template merge-tag sets because a feed item may represent regular content, media-rich records, nested relationships, or WooCommerce products.

Catalog groups

The current feed context contains:

• control and shared tags: if, else, /if, icon, translatable_string;
• nested and field-driven output: feed_from_meta, gallery, video_from_url, button_from_meta, image_from_meta, meta;
• engagement: add_to_favorite, like_button, comments;
• content: post_id, title, post_content, excerpt, permalink;
• dates and author: date, date_updated, author, author_url;
• media: featured_video, featured_image, featured_image_url, video_thumbnail;
• taxonomy: taxonomy_terms;
• WooCommerce: price, display_attribute_info, stock, e_commerce_product_time_slots, e_commerce_product_btn, e_commerce_product_img_from_gallery, sale_text, sale_amount.

This list is a runtime contract. Read each tag’s advertised attributes rather than copying an example from another context.

Practical distinctions

post_content is the feed-context content tag; the single catalog uses content. price renders product pricing, while meta reads a stored custom field and should not be used as a substitute for the WooCommerce-specific contract. feed_from_meta can render related post IDs through another feed template and therefore needs a deliberate non-recursive template choice.

Use conditionals around optional fields, keep buttons linked to real URLs, and validate nested blocks. Product-specific tags may render empty content for non-product items, so do not assign a commerce card to mixed content without checking its fallback design.
