The marker's tooltip is configured with a `tooltip` option which supports all of the tooltip configuration options except `target` and `map` which are provided to the tooltip automatically. The same result as above can be written like this: - -````javascript -L.marker(new L.LatLng(-36.852668, 174.762675), { - tooltip: { - html: "I'm a tooltip!" - } -}).addTo(map); -```` - -###Options - -| Option | Type | Default | Description -| --- | --- | --- | --- -| map | [L.Map](http://leafletjs.com/reference.html#map-class) | `undefined` | The map instance the tooltip is to be shown on (required). -| target | HTMLElement/[L.Marker](http://leafletjs.com/reference.html#marker) | `undefined` | The element or marker to bind the tooltip to. -| html | String | `undefined` | The tooltip content. May also be set using the `L.Tooltip.setHtml()` method. -| width | mixed | `'auto'` | The width of the tooltip. If unspecified the width will be determined by the tooltip content. -| minWidth | mixed | `''` | The minimum width of the tooltip specifed as a number or a valid CSS width value. -| maxWidth | mixed | `''` | The minimum width of the tooltip specifed as a number or a valid CSS width value. -| padding | mixed | `'2px 4px'` | The padding between the tooltip container edge and its content. Specified as a number or a valid CSS padding value. -| showDelay | Number | `500` | Delay in milliseconds before the tooltip displays after the mouse enters the target element. Set to 0 for the tooltip to show immediately. -| hideDelay | Number | `500` | Delay in milliseconds after the mouse exits the target element but before the tooltip actually hides. Set to 0 for the tooltip to hide immediately. -| mouseOffset | [L.Point](http://leafletjs.com/reference.html#point) | `L.point(0, 24)` | An XY offset from the mouse position where the tooltip should be shown. -| fadeAnimation | Bool | `true` | If `true` the tooltip will be faded in when shown. -| trackMouse | Bool | `false` | If `true` the tooltip will follow the mouse as it moves over the target
