--- title: 'Meta' sidebar: order: 8 title: Meta --- The `Meta` block is used to [attach](#attached-vs-unattached) a custom MDX docs page alongside a component’s list of stories. It doesn’t render any content, but serves two purposes in an MDX file: * Attaches the MDX file to a component and its stories, or * Controls the location of the unattached docs entry in the sidebar. {/* prettier-ignore-start */} ```md title="ButtonDocs.mdx" import { Meta } from '@storybook/blocks'; import * as ButtonStories from './Button.stories'; ``` {/* prettier-ignore-end */} The Meta block doesn’t render anything visible. ## Meta ```js import { Meta } from '@storybook/blocks'; ``` `Meta` is configured with the following props: ### `isTemplate` Type: `boolean` Determines whether the MDX file serves as an [automatic docs template](../../writing-docs/autodocs.mdx#with-mdx). When true, the MDX file is not indexed as it normally would be. ### `name` Type: `string` Sets the name of the [attached](#attached-vs-unattached) doc entry. You can attach more than one MDX file to the same component in the sidebar by setting different names for each file's `Meta`. {/* prettier-ignore-start */} ```md title="Component.mdx" import { Meta } from '@storybook/blocks'; import * as ComponentStories from './component.stories'; {/* This MDX file is now called "Special Docs" */} ``` {/* prettier-ignore-end */} ### `of` Type: CSF file exports Specifies which CSF file is [attached](#attached-vs-unattached) to this MDX file. Pass the **full set of exports** from the CSF file (not the default export!). {/* prettier-ignore-start */} ```md title="ButtonDocs.mdx" import { Meta, Story } from '@storybook/blocks'; import * as ButtonStories from './Button.stories'; ``` {/* prettier-ignore-end */} Attaching an MDX file to a component’s stories with the `of` prop serves two purposes: 1. Ensures the MDX content appears in the sidebar inside the component’s story list. By default, it will be named whatever the `docs.defaultName` (which defaults to `"Docs"`) option is set to in `main.js`. But this can be overridden with the [`name` prop](#name). 2. Attaches the component and its stories to the MDX file, allowing you to use other doc blocks in “attached” mode (for instance to use the `Stories` block). The `of` prop is optional. If you don’t want to attach a specific CSF file to this MDX file, you can either use the `title` prop to control the location, or emit `Meta` entirely, and let [autotitle](../../configure/user-interface/sidebar-and-urls.mdx#csf-30-auto-titles) decide where it goes. ### `title` Type: `string` Sets the title of an [unattached](#attached-vs-unattached) MDX file. {/* prettier-ignore-start */} ```md {/* Introduction.mdx */} import { Meta } from '@storybook/blocks'; {/* Override the docs entry's location in the sidebar with title */} ``` {/* prettier-ignore-end */} If you want to change the sorting of the docs entry with the component’s stories, use [Story Sorting](../../writing-stories/naming-components-and-hierarchy.mdx#sorting-stories), or add specific MDX files to your `stories` field in `main.js` in order. ## Attached vs. unattached In Storybook, a docs entry (MDX file) is "attached" when it is associated with a stories file, via `Meta`'s [`of` prop](#of). Attached docs entries display next to the stories list under the component in the sidebar. "Unattached" docs entries are not associated with a stories file and can be displayed anywhere in the sidebar via `Meta`'s [`title` prop](#title).
