# Flux3LayoutPrompt - ComfyUI Built-in Node Documentation

> Builds the layout table that FLUX 3 Image reads from a prompt.

Builds the layout table that FLUX 3 Image reads from a prompt. It takes the elements drawn in the Create Bounding Boxes node and appends them to your prompt as a list of boxes, each with an id, its coordinates, and its description. Cite a box in the prompt as `<obj_N>` to tie words to that region, then connect the output to the prompt input of the FLUX 3 Image node. With no elements connected the prompt is returned unchanged.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `prompt` | The prompt text. Cite box N as `<obj_N>` to tie words to it. | STRING | Yes | - |
| `element` | The elements to place in the layout, taken from the Create Bounding Boxes node. Color palettes are not used, so describe colors in the description instead. | ARRAY | Yes | - |

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `prompt` | The prompt with the box layout table appended, ready to feed into the FLUX 3 Image node. | STRING |
