Lines 157 to 169 in cd3e934

	// Prep each <li>. Give it an index, set its tabindex to -1, add 'keydown' and 'click' event listeners, inject a checkmark auro-icon
	for (let iter = 0; iter < this.options.length; iter += 1) {
	// each option is tabbable
	this.options[iter].setAttribute('tabindex', '0');
	this.options[iter].addEventListener('keydown', (evt) => handleKeyDown(evt));
	this.options[iter].addEventListener('click', (evt) => dispatchEventOptionSelected(Number(evt.target.getAttribute('index')), evt.target.getAttribute('data-value'), evt.target.innerText));
	this.options[iter].addEventListener('focus', (evt) => funcFocus(evt.target));
	this.options[iter].addEventListener('blur', (evt) => funcBlur(evt.target));
	this.options[iter].addEventListener('mouseover', (evt) => funcMouseOver(evt.target));
	this.options[iter].addEventListener('mouseout', (evt) => funcMouseOut(evt.target));
	}
	}
