In example above we show tooltip near some button by "mouseenter" and hide by "mouseleave". For this events you can also use the onHover() decorator:

import Tooltip from 'codex.tooltip';

const someButton = document.getElementById('some-button');

tooltip.onHover(someButton, 'Button helper', {
  placement: 'right',
  delay: 150
