</html>Fractal variants' fields are ignored by Ui Patterns.
However, your Fractal variants needs to have a variant field with the variant machine name as value. Example:
variants:
- name: "scream"
label: "Scream"
context:
variant: "scream"Once ui_patterns_fractal module is installed, copy or link the Fractal's components/ folder into the templates/ folder of any Drupal module or theme, and clear all cache.
Check for the presence of Fractal patterns in Drupal /patterns page (provided by ui_patterns_library module, which is a dependency of ui_patterns_fractal)
