CreateList - ComfyUI Built-in Node Documentation

The Create List node combines multiple inputs into a single, sequential list. It takes any number of inputs of the same data type and concatenates them in the order they are connected. This node is useful for preparing batches of data, such as images or text, to be processed by other nodes in a workflow.

Inputs

Parameter	Description	Data Type	Required	Range
`inputs`	A variable number of input slots named `input`, `input_2`, `input_3`, and so on. Each slot accepts a list of items of the same data type. You can add more slots by clicking the plus (+) icon. All slots must use the same data type (e.g., all IMAGE or all STRING).	Varies	Yes	Any number of slots; each slot accepts any number of items

Note: The node automatically creates new input slots as you connect items. All connected inputs must share the same data type for the node to function correctly. Each connected slot provides a list of items, and the node combines the lists in slot order (input, then input_2, then input_3, …). The node is also searchable under the aliases “Image Iterator”, “Text Iterator”, and “Iterator”.

Outputs

Output Name	Description	Data Type
`list`	A single list containing all the items from the connected inputs, concatenated in the order they were provided. The output data type matches the input data type.	Varies
