Manage Elementor site parts (Theme Builder documents: %s). Bulk operations (1-50) with three actions: "create" makes a new site part as a draft (optionally assigning display conditions in the same call), "update" mutates an existing site part (mutable fields are "conditions" and, for popups only, "display_settings"; body/settings edits go via manage-elements / build-composition / update-page-settings), and "delete" removes a site part. Conditions are slash-separated strings like "include/general" (site-wide), "include/singular/post", "exclude/singular/post/42". Popup "display_settings" holds the Triggers (what opens the popup) and Advanced Rules ("timing": who/when it may show) from the editor Publish Settings dialog; triggers only fire on the front end when the popup has display conditions AND is published. Site parts are NOT published by this tool — they stay drafts and must be published separately (matches the editor UX). For repeating-layout patterns (one single template driven by dynamic data instead of N duplicated pages, include-all + exclude-exceptions condition scoping, Post Content placement), read the elementor://wordpress/best-practices resource before creating singles.
