CustomCombo - ComfyUI Built-in Node Documentation - ComfyUI

The Custom Combo node allows you to create a custom dropdown menu with your own list of text options. It is a frontend-focused node that includes a backend representation to keep your workflow compatible. When you select an option from the dropdown, the node outputs that text as a string and its index position.

Inputs

Parameter	Description	Data Type	Required	Range
`choice`	The text option selected from the custom dropdown. The list of available options is defined by the user in the node’s frontend interface.	COMBO	Yes	User-defined
`index`	An integer value that can be used to specify an index. Default: 0.	INT	No	Any integer (default: 0)

Note: Validation for this node’s inputs is intentionally disabled. This allows you to write any custom text options in the frontend without the backend checking whether your selection matches a predefined list. Widgets other than the combo dropdown are fully defined in the frontend. This node is marked as experimental.

Outputs

Output Name	Description	Data Type
`STRING`	The text string of the option selected from the custom combo box.	STRING
`INDEX`	The index position of the selected option in the dropdown list.	INT
