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.
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

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.

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).

Installation

Ensure the folder containing these files is named Dynamic_sliders_stack.
Place the Dynamic_sliders_stack folder inside your ComfyUI custom_nodes directory.
Restart ComfyUI.

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.
