It is intended for developers and content modelers configuring content types, and should be used when you need to enforce structured data entry with required minimums or capped maximums. ## Minimum and Maximum Limits The **Minimum** and **Maximum Limits** properties let you define the acceptable range for the number of instances a user can add when a field is marked as [Multiple](/docs/developers/create-content-types/multiple/). These settings help enforce structured data entry by ensuring users provide the expected number of values. **Note**: These limits apply only when the **Multiple** option is enabled for a field. They are different from character or value limits set for single-instance fields. You can configure minimum and maximum limits for fields that support multiple instances, including: - **Single Line Textbox**: Define how many textboxes users can add. - **Multi Line Textbox**: Define how many multi line textboxes can be added. - **Rich Text Editor**: Set limits for HTML rich text editor fields. - **JSON Rich Text Editor**: Set limits for JSON RTE fields. - **Markdown**: Control the number of markdown fields users can add. - **Modular Blocks**:**Parent level**: Define the total number of blocks. - **Block-level**: Set limits for how many times a specific block type can be added. - **Number**: Control how many numeric fields users can add. - **Date**: Set limits on the number of date fields allowed. - **File**: Restrict the number of file uploads. - **Link**: Set limits on the number of links users can add. - **Reference**: Limit the number of referenced entries. - **Group**: Control how many instances of the group users can add. - **Global Fields**: Define how many instances of the global field can be added. **Note**: You cannot set minimum or maximum limits for **URL**, **Boolean**, **Custom**, and **Taxonomy** fields. The system validates these limits when users add content. If the number of instances exceeds the maximum or falls below the minimum, a validation message appears, and saving is blocked until the issue is resolved. To set minimum and maximum limits, log in to your [Contentstack account](https://www.contentstack.com/login/), and perform the following steps: - Navigate to your [stack](/docs/developers/set-up-stack/about-stack) and open the content type where you want to set the limits. - Click the field you want to configure. The **Edit Properties** panel appears on the right. - In the **Advanced** tab, enable the **Multiple** toggle. The **Set Minimum Limit** and **Set Maximum Limit** fields will appear. - Under **Set Minimum Limit**, enter the minimum number of instances a user must add. - Under **Set Maximum Limit**, enter the maximum number of instances a user can add. - Since **Modular Blocks** are multiple by default, you can configure limits directly without enabling a Multiple option:**Parent level limits**: Set the total minimum and maximum number of blocks across all types. - **Block-level limits**: Click into a specific block type and define individual min/max limits for that block. - Click **Save** or **Save and Close** to update the content type. ## Example: Enforcing “OR” Logic with Modular Blocks You can use the minimum and maximum limits to simulate **either-or** logic in Modular Blocks. For example, if you want editors to include either a **Video** block or an **Image** block, but not both, in an entry, follow these steps: - Add a **Modular Blocks** field to your content type. - Create two blocks within it: **Video** and **Image**. - In the **Modular Blocks** parent field settings, set the **minimum** and **maximum** limit as **1**. - In the individual **Video** and **Image** blocks, set the maximum limit as **1**. This setup ensures that: - Editors must add **one** block, but cannot add more than one. - As soon as either a **Video** or an **Image** block is added, the maximum limit is reached. - Editors are effectively allowed to choose one of the two—mimicking **OR** functionality. Minimum and maximum limits for **Multiple** fields help guide users and ensure consistent, high-quality content input. With clear limits and in-editor validation, you can streamline content entry while maintaining structure. ## Common questions ### Do minimum and maximum limits work if Multiple is not enabled? No. **Note**: These limits apply only when the **Multiple** option is enabled for a field. ### Which fields do not support minimum or maximum limits? **Note**: You cannot set minimum or maximum limits for **URL**, **Boolean**, **Custom**, and **Taxonomy** fields. ### What happens if an editor exceeds the maximum or goes below the minimum? A validation message appears, and saving is blocked until the issue is resolved. ### Can Modular Blocks have limits without enabling Multiple? Yes. Since **Modular Blocks** are multiple by default, you can configure limits directly without enabling a Multiple option.
