| `delay` | Number or Object | `0` | Delay showing and hiding the tooltip (ms). If a number is supplied, delay is applied to both hide/show. Object structure is: `delay: { "show": 500, "hide": 100 }` |

| `html` | Boolean | `false` | Allow HTML in the tooltip. If true, HTML tags in the tooltip's title will be rendered in the tooltip. If false, the titkle will be inserted as plain text. Use text if you're worried about XSS attacks. |

| `placement` | String or Function | `'top'` | How to position the tooltip - `auto`, `top`, `bottom`, `left`, `right`, `topleft`, `topright`, `bottomleft`, `bottomright`, `lefttop`, `leftbottom`, `righttop`, or `rightbottom`. When `auto` is specified, it will dynamically reorient the tooltip. |

| `title` | String or Element or function | `''` | Default title value if title attribute isn't present. If a function is given, it must return a string. |

| `trigger` | String | `'hover focus'` | How tooltip is triggered: `click`, `hover`, `focus`. You may pass multiple triggers; separate them with a space. |

| `offset` | Number or String | `0` | Offset of the tooltip relative to its target. For more information refer to Popper.js's offset docs. |
