A custom node for ComfyUI that allows you to create lists of prompts with dynamic input count. Add or remove prompt inputs on the fly without creating multiple nodes.

Features

✨ Dynamic Inputs - Adjust the number of prompt inputs from 2 to 50 🔄 Easy Updates - Click "Update inputs" button to add/remove fields 📝 Clean Interface - Multiline text support for each prompt 🎯 List Output - Returns a proper list structure for use with other nodes

Installation

Method 1: Clone to ComfyUI custom_nodes

cd ComfyUI/custom_nodes
git clone <your-repo-url> serhii-prompt-list

Method 2: Manual Installation

1. Download this repository
2. Extract to ComfyUI/custom_nodes/serhii-prompt-list
3. Restart ComfyUI

Usage

Basic Workflow

1. Add Node: Search for "Dynamic Prompt List" in ComfyUI node menu
2. Set Input Count: Adjust the inputcount parameter (default: 5)

How It Works

Python Backend (prompt_list_node.py)

• Defines the node class with dynamic **kwargs support
• Processes inputs dynamically based on inputcount
• Returns a list of non-empty prompts

JavaScript Frontend (dynamic_inputs.js)

• Adds "Update inputs" button to the node
• Dynamically creates/removes input slots in the UI
• Handles input counting and name management

Troubleshooting

Node doesn't appear in menu

• Restart ComfyUI completely
• Check console for error messages
• Verify files are in the correct directory structure

"Update inputs" button doesn't work

• Make sure JavaScript file is in web/js/ folder
• Clear browser cache and refresh ComfyUI
• Check browser console for JavaScript errors

Inputs not connecting

• Ensure you clicked "Update inputs" after changing count
• Verify the input type matches (STRING)
