Main Article: Building Character Sheets

This is an example for selecting attributes to be included in a Sheet Roll.

The key components are:

  • Update display of toggle buttons based on the associated flag, using Styling Checkboxes and Radios
  • Attribute name, button name, flag attribute name, and translation key all share the same base value.
  • Displaying the selected attributes (based on translation key)
  • Selected attribute list and dice pool value are stored in hidden input fields.
  • Roll button references the dice pool attribute with Auto-Calculating Values

[edit] HTML
