# ComfyUI-IterSwitch
A set of dynamic switch nodes for ComfyUI, designed to simplify complex workflows by allowing flexible, iterative input selection. These nodes provide dynamic connection management and intelligent fallback logic.

## Key Features
Dynamic Inputs: Automatically resizes the number of input connections based on the input_count widget.

## Smart Fallback: 
With the use_last_input option enabled, the node can search backwards from the current index to find the nearest valid (connected) input, ensuring a result is always returned.

## Type Support: 
Includes switches for Text, Conditioning, CLIP, Image, Model, and Float types.

### Example Usage: Iter_TextSwitch
The Iter_TextSwitch node allows you to combine a base string with one of many dynamically connected inputs.

1. Basic Connection
The node takes an add_text input (base string) and allows you to dynamically define multiple text inputs. You can select the specific input using output_index.

2. Fallback Logic
When use_last_input is enabled, the node becomes more robust. If your current output_index points to a disconnected or empty input, the node will automatically search backwards through your inputs until it finds the most recent valid (connected) string.

3. Iterative Workflow
By using the output_index, you can easily integrate this node into iterative loops, ensuring that your text prompts are dynamically selected or concatenated based on your workflow state.
