This documentation describes one or more public beta features that are in development. Beta features are subject to quick, iterative changes; therefore the current user experience in the Sigma service can differ from the information provided in this page. This page should not be considered official published documentation until Sigma removes this notice and the beta flag on the corresponding feature(s) in the Sigma service. For the full beta feature disclaimer, see [Beta features](/docs/sigma-product-releases#beta-features). This is an example representation of a workbook, retrieved using the [Get a workbook](/reference/get-workbook) endpoint with the query parameter `includeContents=true`. Representations like this one can be used to create a workbook from code using the [Create a workbook](/reference/create-workbook) endpoint. Each page in this example library includes the code representation of the workbook and step-by-step instructions to create it in the Sigma UI. Consult this example and others in the [Workbook representation example library](/docs/workbook-representation-example-library) to: * Troubleshoot the formatting of a particular feature in code representation * Relate a feature from the Sigma UI to its representation in code * Provide context to AI tools used to create workbooks from code This example representation cannot be used as-is. All identifying details, such as IDs, names, and URLs, have been replaced with randomized ID values or generic substitutions. The format of these contents, like the length of ID values, is preserved for demonstrative purposes. However, this representation cannot be directly used without modification to the base URL, connection details, and more. For more information, see [Create and manage workbooks from code](/docs/manage-workbooks-as-code). ## System and user requirements To complete the steps in this example, you must meet the user requirements listed below for creating the workbook in the UI and creating it from code. The ability to create this workbook in the Sigma UI requires the following: * You must be assigned an [account type](/docs/account-type-and-license-overview) with the **Create, edit, and publish workbooks** permission enabled. * You must have access to a connection to a data platform. The ability to create a workbook from code requires the following: * You must be assigned an [account type](/docs/account-type-and-license-overview) with the **Create, edit, and publish workbooks** permission enabled. * You must have developer credentials for the Sigma API. For more information, see [Get started with the Sigma REST API](/reference/get-started-sigma-api). This example uses a table from the [Sigma Sample Connection](/docs/sigmas-sample-connection). Your organization might have disabled access to the Sigma sample connection. If so, you can contact an admin to enable it, or use a table from another connection to follow along with this example. ## Create the example workbook in the Sigma UI This example shows a workbook with a button that displays a specific tab in a tabbed container using the **Select tab** action. To create this workbook in the Sigma UI: 1. Go to the **Home** page. 2. Select ![](https://sigma-docs-screenshots.s3.us-west-2.amazonaws.com/Icons/button-add.svg) **Create new** > **Workbook**. A new workbook opens. 3. From the **Add element** bar, select **UI** > **Button**. 4. From the **Add element** bar, select **Layout** > **Tabbed container**. The tabbed container appears in the workbook. 5. In the **Add element** bar, select **UI** > **Text** and drag the text element into **Tab 1** in the tabbed container. 6. In the text element, enter `This is tab 1.` 7. Open **Tab 2** of the tabbed container. 8. In the **Add element** bar, select **UI** > **Text** and drag the text element into **Tab 2**. 9. In the text element, enter `This is tab 2.` 10. Select the button element. 11. In the editor panel, open the **Actions** tab. 12. Select ![](https://sigma-docs-screenshots.s3.us-west-2.amazonaws.com/Icons/button-add.svg) **Add action**. 13. Configure the action with the following settings: | Option | Setting | | :------------------- | :------------------- | | **Action** | **Select tab** | | **Tabbed container** | *Tabbed Container 1* | | **Tab** | *Tab 2* | 14. In the document header, select **Save as**. 15. Enter a name for the workbook, such as `select-tab-action`. 16. Select **Save**. ## Get a code representation of this workbook To get a representation of this workbook, follow the steps in [Get the code representation of a workbook](/docs/get-the-code-representation-of-a-workbook). The code representation of this workbook appears like the following: #### YAML representation ```yaml workbookId: 5cadefe9-c5e1-4a2a-8e20-b84b31ffd9c9 workbookUrlId: CGkq9uQHVaD9jfEaxwcyhl createdBy: zgzXpTRVbfX4ZE9TEm9q9fUsfXZ5o updatedBy: zgzXpTRVbfX4ZE9TEm9q9fUsfXZ5o createdAt: '2026-08-13T23:36:38.314Z' updatedAt: '2026-08-14T22:07:59.970Z' name: select-tab-action url: https://aws-api.sigmacomputing.com/org-name/workbook/CGkq9uQHVaD9jfEaxwcyhl path: My Documents/ latestVersion: 2 ownerId: zgzXpTRVbfX4ZE9TEm9q9fUsfXZ5o isArchived: false contents: schemaVersion: 1 elements: - id: 8iSJWXqXEQW kind: button text: Click Me appearance: filled actions: - id: tlCcJnQVjPN trigger: on-click effects: - effect: select-tab tabbedContainerElementId: MMeiwOMt3Yc selectedTab: type: tab index: 1 - id: MMeiwOMt3Yc kind: tabbed-container tabs: - name: Tab 1 - name: Tab 2 - id: aVohnFEdBPq kind: text body: This is tab 1. - id: WcI88Z4exUd kind: text body: This is tab 2. pages: - id: i2Tg7D6BZT name: Page 1 kind: workbook layout: | documentVersion: 2 ``` ## Representing the select tab action #### Select tab action representation ```yaml ... actions: - id: tlCcJnQVjPN trigger: on-click effects: - effect: select-tab tabbedContainerElementId: MMeiwOMt3Yc selectedTab: type: tab index: 1 ... ```
