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. 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:
- Group: Control how many instances of the group users can add.
- Global Fields: If the Global field is set as multiple, define how many instances it can have.
- Reference: Limit how many entries can be referenced.
- 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.
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, and perform the following steps:
- Navigate to your 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.

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.
