Modify an existing page or snippet's widget tree in place with ALTER PAGE / ALTER SNIPPET — SET, INSERT, DROP, REPLACE and SET Layout. Use when changing a caption, style or property, adding or removing a widget, or reordering a form, instead of rewriting the whole page with CREATE OR REPLACE. The only safe way to change a page or snippet authored in Studio Pro.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# ALTER PAGE / ALTER SNIPPET - Modify Existing Pages and Snippets

## Overview

ALTER PAGE and ALTER SNIPPET modify an existing page or snippet's widget tree **in-place** without requiring a full `create or modify`. Operations work directly on the raw BSON tree, preserving widget types and properties that MDL doesn't explicitly model.

| Scenario | Use |
