DCTestNode - ComfyUI Built-in Node Documentation - ComfyUI

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"` `"option2"` `"option3"` `"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"` `"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
