Manage a Composition

Note: Studio is currently available as part of an Early Access Program and may not be accessible to all users. For more information or to request access, contact our support team.

A composition is the foundational unit of structure in Studio. It can represent a full page, a section of a page, or a reusable UI module. After creating a project, you use compositions to define layouts, bind content, and apply design rules.

A composition typically combines the following elements:

• UI components
• CMS data bindings
• Design tokens and responsive rules
• Optional page-level metadata

You can create multiple compositions within a project and bind content entries to them.

Studio supports two types of compositions: Linked and Freeform. Choosing the right type ensures your layout aligns with your content strategy.

A Linked Composition connects a page to a specific Content Type in your stack. Once linked, the composition dynamically renders content from different entries—based on the URL opened.

• Create repeatable layouts driven by content entries
• Bind to a Content Type and define a URL Slug
• Ideal for blogs, product pages, or any template used across multiple entries
• Supports dynamic rendering for scalable content strategies

Tip: Linked Compositions work best when a Content Type has multiple entries or when you want to build a shared template for entry-based pages.

For example, you are building a “Blog” section. You create a Linked Composition and connect it to the “Blog Posts” Content Type. Each blog post entry (e.g., /blog/hello-world, /blog/whats-new) dynamically uses this layout via the slug.

A Freeform Composition is not tied to a Content Type. It is ideal for static, standalone, or draft pages.

• No dependency on content types
• Define a custom URL Path
• Best suited for landing pages, microsites, or one-off campaigns
• Works well with singleton Content Types for unique layouts

Tip: Start with a Freeform Composition if you don’t yet have content entries. You can convert it to a Linked Composition later.

For example, you are designing a one-off “Spring Campaign” landing page. Since it doesn’t pull data from any Content Type, you use a Freeform Composition and set the URL path as /campaigns/spring-2025.

Each composition type requires a URL structure:

• URL Slug for Linked Compositions: The final segment of the page's route, generated from the entry title. Slugs are tied to entries, making them reusable across templates.

  Example: /company/about-us, where about-us is the slug.

• URL Path for Freeform Compositions: The full path to the page, manually defined.

  Example: /campaigns/fall-2025

  Tip: Use slugs for dynamic, entry-driven pages. Use paths for static, one-off pages.

Keeping composition URLs up to date ensures your site stays structured, relevant, and aligned with your goals.

To build layouts and structure content visually in Studio, you must start by creating a composition. A composition acts as a container where you can arrange UI components, bind CMS data, and apply design rules. You can create compositions from scratch or link them to existing content types for dynamic content rendering.

To create a composition, log in to your Contentstack account and perform the following steps:

1. Select Studio from the “App Switcher”.
2. Navigate to your Project and click New Composition.
3. In the modal, select the type of composition: Linked or Freeform.
4. Select the Composition Type:
   1. Linked Composition: Best for dynamic templates that render multiple entries from a Content Type.

      Select the Content Type and specify a URL Slug (e.g., /blog/:slug).

   2. Freeform Composition: Ideal for standalone or one-off pages (e.g., landing pages using singleton Content Types).

      Provide a custom URL Path (e.g., /marketing/launch).

5. Enter the Name of your composition.
6. The UID auto-generates based on the name. You can customize it.
7. Click Create to open the composition editor.

You can update a composition’s metadata, such as its name, content type, URL slug, or URL path, directly from the composition listing page. This is different from editing the layout or bindings inside the canvas.

To edit a composition’s metadata, open your Studio project and perform the following steps:

1. Locate the composition you want to edit. Click the vertical ellipsis and select Edit.
2. In the Edit Composition modal, update the required fields:
   1. Name: Update the composition’s display name.
   2. Content Type (only visible for linked compositions): Choose or update the content type this composition is connected to.
   3. URL Slug (only visible for linked compositions): Define the URL structure for this composition. You can use wildcards for dynamic routing (e.g., /blog/*).
   4. URL Path (only visible for freeform compositions): Define the URL path for this composition.

      Note: The UID of a composition cannot be edited.

3. To change the composition type, expand Advanced Options:
   1. If you are editing a linked composition, you can see an option to convert it to a freeform composition.
   2. If you are editing a freeform composition, you can see the option to convert it to a linked composition by connecting it to a content type.

      Note: Converting between modes affects how the composition binds to entries. A linked composition binds to a single content type. A freeform composition can be reused across multiple content types.

4. Click Save to confirm your changes.

If a composition is no longer needed, you can delete it from your project. This helps reduce clutter and ensures that only relevant layouts are retained.

Warning: Once you delete a composition, it cannot be recovered.

To delete a composition, open a Studio project and perform the following steps:

1. Locate the composition you want to delete. Click the vertical ellipsis and select Delete.
2. Confirm your action in the Delete Composition modal.

As your project grows, organizing compositions becomes essential for ease of access and maintenance. Studio offers tools to search, rename, duplicate, and reorder compositions from the dashboard, helping you keep everything structured and discoverable.

From the project dashboard, you can:

• Search compositions by name
• Rename or delete any composition
• Sort for improved visibility
• Preview how they appear in your target layout

Follow these guidelines to ensure scalable and maintainable compositions:

• Use meaningful names (e.g., “Product Card Template”).
• Prefer Linked Compositions for dynamic content.
• Combine Studio with design systems and custom components for efficiency.

Compositions give you the flexibility to design, manage, and scale pages visually in Studio. Whether you’re building dynamic layouts or simple modules, keeping your compositions organized and up to date helps your team work faster and stay aligned.
