Global configuration

[tomickigrzegorz]

It would be useful to have a global configuration when we have only one element type to shorten. Instead of adding to each data-config item, add one global when calling the function.

document.addEventListener('DOMContentLoaded', function () {
  new ShowMore('.element', {
    config: {
      "type": "text",
      "limit": 120,
      "more": "→ read more",
      "less": "← read less"
    }
  });
});
