# DCTestNode - ComfyUI Built-in Node Documentation

> DCTestNode is a logic node that returns different types of data based on a user's selection from a dynamic combo box.

DCTestNode is a logic node that returns different types of data based on a user's selection from a dynamic combo box. It acts as a conditional router, where the chosen option determines which input field is active and what type of value the node will output.

## Inputs

The node uses a dynamic combo selector: the `combo` parameter is always visible, and the other input fields appear only when their corresponding option is selected.

### Common Inputs

| Parameter | Description                                                                                   | Data Type      | Required | Range                                                          |
| --------- | --------------------------------------------------------------------------------------------- | -------------- | -------- | -------------------------------------------------------------- |
| `combo`   | The main selection that determines which input field is active and what the node will output. | DYNAMIC\_COMBO | Yes      | `"option1"`<br />`"option2"`<br />`"option3"`<br />`"option4"` |

### option1 Inputs

| Parameter | Description                                                                                    | Data Type | Required | Range |
| --------- | ---------------------------------------------------------------------------------------------- | --------- | -------- | ----- |
| `string`  | A text input field. This field is only active and required when `combo` is set to `"option1"`. | STRING    | Yes      | -     |

### option2 Inputs

| Parameter | Description                                                                                            | Data Type | Required | Range |
| --------- | ------------------------------------------------------------------------------------------------------ | --------- | -------- | ----- |
| `integer` | A whole number input field. This field is only active and required when `combo` is set to `"option2"`. | INT       | Yes      | -     |

### option3 Inputs

| Parameter | Description                                                                                      | Data Type | Required | Range |
| --------- | ------------------------------------------------------------------------------------------------ | --------- | -------- | ----- |
| `image`   | An image input field. This field is only active and required when `combo` is set to `"option3"`. | IMAGE     | Yes      | -     |

### option4 Inputs

When `combo` is set to `"option4"`, the node shows a second dynamic combo selector (`subcombo`) that controls a nested set of input fields.

| Parameter  | Description                                                                                                                              | Data Type      | Required | Range                  |
| ---------- | ---------------------------------------------------------------------------------------------------------------------------------------- | -------------- | -------- | ---------------------- |
| `subcombo` | A secondary dynamic combo selection that appears when `combo` is set to `"option4"`. It determines which nested input fields are active. | DYNAMIC\_COMBO | Yes      | `"opt1"`<br />`"opt2"` |
| `float_x`  | A decimal number input. This field is only active and required when `combo` is set to `"option4"` and `subcombo` is set to `"opt1"`.     | FLOAT          | Yes      | -                      |
| `float_y`  | A decimal number input. This field is only active and required when `combo` is set to `"option4"` and `subcombo` is set to `"opt1"`.     | FLOAT          | Yes      | -                      |
| `mask1`    | A mask input field. This field is only active when `combo` is set to `"option4"` and `subcombo` is set to `"opt2"`. It is optional.      | MASK           | No       | -                      |

**Parameter Constraints:**

* The `combo` parameter controls the visibility and requirement of all other input fields. Only the inputs associated with the selected `combo` option will be shown and are required (except for `mask1` which is optional).
* When `combo` is set to `"option4"`, the `subcombo` parameter becomes required and controls a second set of nested inputs (`float_x`/`float_y` or `mask1`).

## Outputs

| Output Name | Description                                                                                                                                                                                               | Data Type |
| ----------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- |
| `output`    | The output depends on the selected `combo` option. It can be a STRING (`"option1"`), an INT (`"option2"`), an IMAGE (`"option3"`), or a string representation of the `subcombo` dictionary (`"option4"`). | ANYTYPE   |
