--- title: Tooltip lang: en-US --- # Tooltip Display prompt information for mouse hover. ## Basic usage Tooltip has 9 placements. :::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. tooltip/basic ::: ## Theme Tooltip has two themes: `dark` and `light`。 :::demo Set `effect` to modify theme, and the default value is `dark`. tooltip/theme ::: ## More Content Display multiple lines of text and set their format. :::demo Override attribute `content` of `el-tooltip` by adding a slot named `content`. tooltip/rich-content ::: ## Advanced usage 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. :::demo tooltip/advanced-usage ::: :::tip 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. ::: ## Attributes | Attribute | Description | Type | Accepted Values | Default | | --------------------- | ----------------------------------------------------------------------------------------------------------------------------- | ------- | --------------------------------------------------------------------------------------------------------- | ------------------------------------------------------- | | append-to-body | whether to append Dialog itself to body.
