The AutogrowPrefixTestNode is a logic node designed to test the autogrow input feature. It accepts a dynamic number of float inputs, combines their values into a comma-separated string, and outputs that string.

## Inputs

| Parameter  | Data Type | Required | Range          | Description                                                                                                   |
| ---------- | --------- | -------- | -------------- | ------------------------------------------------------------------------------------------------------------- |
| `autogrow` | AUTOGROW  | Yes      | 1 to 10 inputs | A dynamic input group that can accept between 1 and 10 float values. Each input in the group is a FLOAT type. |

**Note:** The `autogrow` input is a special dynamic input. You can add multiple float inputs to this group, up to a maximum of 10. The node will process all provided values.

## Outputs

| Output Name | Data Type | Description                                                                 |
