# Conditional content Conditional content blocks let you control who can see a given block of content on your page based on user data and variables. These variables can be passed in via cookies, feature flags, authenticated access, or URL parameters. ### Create conditional content To add a conditional block, begin a new line in the editor, type /, then select The Page condition icon in GitBook **Conditional content**. After inserting the block, click the red condition badge in the top right of the block. Clicking this will allow you to add a condition through the [condition editor](/docs/site-access/adaptive-content/adapting-your-content.md#working-with-the-condition-editor). You’ll be able to write your condition as an [expression](https://gitbook.com/docs/creating-content/variables-and-expressions) that will run against data defined in your site. You can reference data from [variables](/docs/creating-content/variables-and-expressions.md), or data coming from visitors through their [claims](/docs/site-access/adaptive-content/enabling-adaptive-content.md#set-your-visitor-schema). See [adaptive content](/docs/site-access/adaptive-content.md) for more details. ### Example The examples below use a URL parameter linked from the button to control which conditional content block is visible. {% if visitor.claims.unsigned.example\_attribute\_A %} This block is only visible to users **with** attribute A. View without attribute A {% endif %} {% if !visitor.claims.unsigned.example\_attribute\_A %} This block is only visible to users **without** attribute A. View with attribute A {% endif %} ## Representation in Markdown ```markdown ## Example {% if visitor.claims.unsigned.example_attribute_A %} This block is only visible to users **with** attribute A. View without attribute A {% endif %} {% if !visitor.claims.unsigned.example_attribute_A %} This block is only visible to users **without** attribute A. View with attribute A {% endif %} ``` --- # 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.
