Customize via Javascript

There isn’t an option for everything, but there is a way to achieve almost everything with Javascript.

Add size attribute to the time selectors.

The below Javascript code changes the hour and time selector to have more time options visible at once.

document.addEventListener('DOMContentLoaded', function () {
	const findASWBSelect = document.querySelectorAll(".calendar-time select");
	
	if (findASWBSelect) {
		findASWBSelect.forEach(element => {
			element.setAttribute("size", "4");
		});
	}
});
