CreateList - ComfyUI Built-in Node Documentation - ComfyUI

The Create List node combines multiple inputs into a single, sequential list. It accepts any number of input slots that share the same data type and concatenates their items in the order the slots are connected. The result is one list containing all connected items.

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 (for example, all IMAGE or all STRING). New slots are created automatically as needed. The node concatenates the lists in slot order.	Any	Yes	Any number of slots; each slot accepts any number of items

Note: All connected inputs must share the same data type. 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 items from the connected inputs, concatenated in the order the slots were provided. The output data type matches the input data type.	Any
