plugins:
  - panzoom:
      include_selectors:
        - .myClass # class in html
        - "#myId" # id in html
        - "img" # tag in html
      exclude_selectors:
        - ".mermaid"
        - ".d2"

Exclude items

To exclude a single item add the class pz-ignore. Example for an image

Hint

This makes the hint on how to use it permanently visible.

plugins:
  - panzoom:
      always_show_hint: true # default false

This changes the location of the hint

plugins:
   - panzoom:
      hint_location: "top" # default bottom

Hide hint completely

plugins:
   - panzoom:
      hint_location: "disabled" # default bottom

Use different key

Options for activation key are:

• alt
• ctrl
• shift
• none

plugins:
  - panzoom:
      key: "ctrl" # default alt

Set Initial Zoom Level

This sets the initial zoom level for all diagrams and images.

plugins:
  - panzoom:
      initial_zoom_level: 1.5 # default 1.0

Exclude Pages

Enable Fullscreen

plugins:
  - panzoom:
      full_screen: True # default False

Automatic Zoom State Persistence

The plugin automatically saves the zoom level and pan position for each diagram to your browser's localStorage. This means:

• Persistent Settings: Your preferred zoom level and position for each diagram are remembered across page reloads
• Per-Diagram Memory: Each diagram on a page maintains its own zoom state independently
• Automatic Cleanup: Saved states older than 30 days are automatically cleared
• Reset Functionality: Using the reset button clears the saved state for that diagram and returns to the configured initial zoom level

This feature works automatically - no additional configuration is required. The zoom states are stored locally in your browser and are not shared between different browsers or devices.
