Add Container is a WordPress ability from The Plus Addons for Elementor — usable via Easy MCP AI, which connects Claude, ChatGPT, and any AI assistant to your site.
Install Free Plugin →Add Container
WriteAdds a flex or grid container to a page, optionally nested inside a parent container.
Requires the The Plus Addons for Elementor plugin (which registers under the 'tpae' ability category) on WordPress 6.9+, with Elementor active. Every ability requires the current user to have the 'edit_posts' capability (and 'edit_post' for the specific post being modified); abilities that create or edit content also verify Elementor and, where relevant, the target The Plus widget are available. A subset of abilities (theme templates, template conditions, dynamic tags, popups, and some custom-code abilities) only register when Elementor Pro is active, and many widget abilities load only in the free plugin when the Pro add-on is inactive.
What it does
execute_add_container requires post_id, loads page data, builds a new container element via factory->create_container(settings) (marking it isInner when a parent_id is given), inserts it into the tree at the given position under parent_id (or top-level) via data->insert_element(), saves the page, and returns the new element_id and post_id, or a WP_Error if the specified parent isn't found.
