DCTestNode - ComfyUI Built-in Node Documentation

The 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

Parameter	Description	Data Type	Required	Range
`combo`	The main selection that determines which input field is active and what the node will output.	COMBO	Yes	`"option1"` `"option2"` `"option3"` `"option4"`
`string`	A text input field. This field is only active and required when `combo` is set to `"option1"`.	STRING	No	-
`integer`	A whole number input field. This field is only active and required when `combo` is set to `"option2"`.	INT	No	-
`image`	An image input field. This field is only active and required when `combo` is set to `"option3"`.	IMAGE	No	-
`subcombo`	A secondary selection that appears when `combo` is set to `"option4"`. It determines which nested input fields are active.	COMBO	No	`"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	No	-
`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	No	-
`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
