# Dynamic Sliders Stack for ComfyUI
![slider_stacker and slider_receiver](dynamic_slider_stacker_reciever_nodes.png)
![Slider Stacker and Slider Receiver](dynamic_slider_stacker_reciever_nodes.png)
A custom node pack for ComfyUI providing a stack of named sliders with dynamic behavior.
## Features
---
* **Slider Stacker**: A node with a configurable number of named sliders (up to 50).
* **Slider Receiver**: Extracts the weight value of a specific slider from the stack output based on its index.
* **Dynamic Max Strength**: Adjusting the `slider_max_strength` scales all individual sliders proportionally.
![Scaling](scaling.gif)
* **Dynamic Individual Sliders**: Adjusting an individual `slider_wt` updates the `slider_max_strength` to reflect the new highest value among all sliders.
* **String Output**: The `Slider Stacker` outputs a comma-separated string of the current weights for all active sliders.
* **Dynamic UI**: The stacker node automatically shows/hides slider input rows based on the `slider_count` setting.
* **Context Menu**: Right-click options for batch slider operations (Average, Reset, Set All to Max/Min).

## 📌 Nodes Overview
### Slider Stacker
* **Inputs**:
* `slider_max_strength` (FLOAT): The master maximum value. Adjusting this scales all sliders below it.
* `slider_count` (INT): Controls how many slider rows are visible and processed (1-50).
* `slider_name_{i}` (STRING): A text field to name or describe the slider (optional).
* `({i})` (FLOAT Widget): The individual weight for this slider (0.0-2.0). Adjusting this updates the `slider_max_strength` if this slider becomes the new maximum. (Widget name uses parentheses around the index).
* **Output**:
* `SLIDER_WEIGHTS` (STRING): A comma-separated string of the weight values for sliders 1 through `slider_count`, formatted to two decimal places (e.g., "1.00, 0.50, 0.75").
* **Right-Click Options**:
* `Average Slider Values`: Sets all visible sliders to their average value.
* `Reset Slider Values`: Sets all visible sliders to the default value (1.0).
* `Set All to Max Value`: Finds the highest value among visible sliders and sets all visible sliders to that value.
* `Set All to Min Value`: Finds the lowest value among visible sliders and sets all visible sliders to that value.

- `Set All to Min Value`: Finds the lowest value among visible sliders and sets all visible sliders to that value.

### Slider Receiver
* **Inputs**:
* `weights_string` (STRING): Connect the `SLIDER_WEIGHTS` output from the `Slider Stacker` here.
* `index` (INT): The 1-based index of the slider whose weight you want to extract (1-50).
* **Output**:
* `WEIGHT` (FLOAT): The floating-point value of the slider at the specified index (returns 0.0 if index is out of bounds or input is invalid).
- **Inputs**:
- `weights_string` (STRING): Connect the `SLIDER_WEIGHTS` output from the `Slider Stacker` here.
- `index` (INT): The 1-based index of the slider whose weight you want to extract (1-50).
## Installation
- **Output**:
- `WEIGHT` (FLOAT): The floating-point value of the slider at the specified index (returns 0.0 if the index is out of bounds or input is invalid).

## 💡 Use Case Scenarios
This node setup provides a centralized control panel for managing multiple numerical weights within your workflow. Here are a few examples:
* **Multiple LoRA Weights:** Assign each slider to a different LoRA. Use the `Slider Stacker` to adjust the overall impact (`slider_max_strength`) or fine-tune individual LoRA weights. Use `Slider Receiver` nodes to pipe the individual weights into the `strength_model` and/or `strength_clip` inputs of `LoRA Loader` nodes.
* **Prompt Segment Weighting:** If using nodes that allow weighting different parts of a prompt (e.g., via attention syntax or specialized nodes), you could use sliders to control the emphasis on different elements like `(subject:WEIGHT)`, `(style:WEIGHT)`, `(background:WEIGHT)`. Connect `Slider Receiver` outputs to the relevant weight inputs.
* **Embedding/Textual Inversion Strength:** Control the influence of multiple embeddings by connecting `Slider Receiver` outputs to nodes that adjust their strength (if available).
* **Style/Character Consistency:** If you have multiple elements defining a style or character (multiple LoRAs, specific prompt weights), group their controls onto one `Slider Stacker` for easier holistic adjustments.
* **Controlling Custom Node Parameters:** Any custom node that accepts a FLOAT input for strength, influence, weight, etc., can potentially be controlled by connecting a `Slider Receiver`'s output to it.
* **Centralized Control Panel:** Create a 'dashboard' near the start of your workflow using one or more `Slider Stacker` nodes to manage key weights without needing to hunt down individual nodes later in the graph.
- **Multiple LoRA Weights**: Assign each slider to a different LoRA. Use the `Slider Stacker` to adjust the overall impact (`slider_max_strength`) or fine-tune individual LoRA weights. Use `Slider Receiver` to retrieve specific weights.
- **Prompt Segment Weighting**: Control the emphasis of different parts of a prompt.
- **Embedding/Textual Inversion Strength**: Manage multiple embeddings by connecting `Slider Receiver` outputs to nodes that adjust their strength.
- **Style/Character Consistency**: Group controls for multiple elements (LoRAs, weights) onto one `Slider Stacker` for centralized adjustments.
- **Controlling Custom Node Parameters**: Control FLOAT inputs for strength, weight, etc., in custom nodes with `Slider Receiver` outputs.
- **Centralized Control Panel**: Use one or more `Slider Stacker` nodes to create a 'dashboard' for managing weights.
