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 new Elementor flex container to a page or nests it inside another existing 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
This ability loads the target post's Elementor element tree, builds a new container element with a generated ID and default settings (content_width boxed, container_type flex) merged with any settings you supply, then inserts it either at the top level of the page or inside a given parent_id at the requested position (append by default). It saves the updated Elementor data back to the post and returns the new element's ID. It fails with a WP_Error if Elementor is not active, post_id is missing, or the specified parent container cannot be found.
