:::demo Use attribute `content` to set the display content when hover. The attribute `placement` determines the position of the tooltip. Its value is `[orientation]-[alignment]` with four orientations `top`, `left`, `right`, `bottom` and three alignments `start`, `end`, `null`, and the default alignment is null. Take `placement="left-end"` for example, Tooltip will display on the left of the element which you are hovering and the bottom of the tooltip aligns with the bottom of the element.
In addition to basic usages, there are some attributes that allow you to customize your own:
`transition` attribute allows you to customize the animation in which the tooltip shows or hides, and the default value is el-fade-in-linear.
`disabled` attribute allows you to disable `tooltip`. You just need set it to `true`.
In fact, Tooltip is an extension based on [Vue-popper](https://github.com/element-component/vue-popper), you can use any attribute that are allowed in Vue-popper.
The `router-link` component is not supported in tooltip, please use `vm.$router.push`.
Disabled form elements are not supported for Tooltip, more information can be found at [MDN](https://developer.mozilla.org/en-US/docs/Web/Events/mouseenter). You need to wrap the disabled form element with a container element for Tooltip to work.
