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.

Theme

Tooltip has two built-in themes: dark and light。

:::tip

To use customized theme, you will have to known where your tooltip is rendered into, if your tooltip is rendered into the root element, you will need to set the css rule globally.

It is recommended that not using linear gradient background color when you using customized theme and showing the arrow at the same time, because the popup arrow and the content is two different elements, the popup arrow's style needs to be set individually, and when it comes to the gradient background color, it might seem a little bit weird.

:::

:::demo Set effect to modify theme, and the default value is dark.

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.

:::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. You need to wrap the disabled form element with a container element for Tooltip to work.

:::

HTML as content

The content attribute can be set to HTML string.

:::warning

Although content property supports HTML strings, dynamically rendering arbitrary HTML on your website can be very dangerous because it can easily lead to XSS attacks. So when raw-content is on, please make sure content is trusted, and never assign user-provided content.

Virtual triggering

Sometimes we want to render the tooltip on some other trigger element, we can separate the trigger and the content.

:::tip

Virtual triggering tooltip is controlled component, so that you will have to control the visibility of the tooltip your own when this happens, YOU WILL NOT be able to close the tooltip by clicking somewhere else.
