# Page Fragment ## Description: Page Extension Page fragments allow you to create reusable components of a page, like address form, order detail popup etc. Page fragments can also update dynamically based on conditions. If you make a change to a fragment, every instance of the fragment in the app updates to match, including those you've already added to pages. This is similar to reference item in the previous versions, with support for dynamic content based on rules/conditions. ### Allowed Parent Components: 1. Card Body 2. Col 3. Horizontal Section 4. Scroll Layout 5. Vertical Section ### Allowed Child Components: No child available ### Properties ### ➤ Page Fragment ID Allowed Values: Free text field --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.cloudio.io/ui-components/widgets/pageextension.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
