Usage

NS-FlexPreset Node

1. Add Node: Find "NS Flex Preset" in the "NS" category of the node menu

2. Create/Edit YAML Presets:

   • YAML files are saved in ComfyUI/custom_nodes/ComfyUI-NS-Util/nodes/presets/
   • Example YAML structure:

    positive prompt:
      type: string
      value: daytime sky nature dark blue galaxy bottle
    negative prompt:
      type: string
      value: text, watermark
    steps:
      type: int
      value: '22'
    cfg:
      type: float
      value: '4.55'
   

3. Using in ComfyUI:

   • Select a YAML file from select_yaml
   • Select or enter select_preset
   • The node automatically creates typed output ports for each value
   • Connect these outputs to other nodes in your workflow

4. Editing Values in UI:

   • Click "Add Value" to create new preset values
   • Change values directly on the node
     • For int/float, the input widget becomes a slider - click to input, drag left/right to adjust values
   • How to delete values:
     • Select key name in select_value -> Click Delete [key name] button
     • If Names are duplicated, the last entered value is kept and others are deleted
   • All changes are automatically saved to the YAML file
   • You can also edit YAML directly
     • If edited while ComfyUI is running, switch presets or refresh the browser

Node Interface

• select_yaml: Choose from available YAML files
• select_title: Choose from existing preset titles in the selected YAML
• input_title: Input custom title (creates new if doesn't exist)
• Value Panel: Display and edit each preset value:
  • Name (editable)
  • Type selector (int/float/string)
  • Value input field
• Add/Delete Buttons: Manage preset values

Requirements

• ComfyUI (0.3 or later recommended, other versions not tested)
• Python packages (automatically included with ComfyUI):
  • pyyaml
  • watchdog
  • aiohttp

Roadmap

This is the first node in the NS-Util collection. Future additions planned:

• ManySliders
  • Will be redesigned to be switchable with presets before addition
