Dialog
Informs users while preserving the current page state.
TIP
This component requires the <client-only></client-only> wrap when used in SSR (eg: Nuxt) and SSG (eg: VitePress).
Basic usage
Dialog pops up a dialog box, and it's quite customizable.
TIP
before-close only works when user clicks the close icon or the backdrop. If you have buttons that close the Dialog in the footer named slot, you can add what you would do with before-close in the buttons' click event handler.
Customized Content
The content of Dialog can be anything, even a table or a form. This example shows how to use Element Plus Table and Form with Dialog.
Customized Header
The header slot can be used to customize the area where the title is displayed. In order to maintain accessibility, use the title attribute in addition to using this slot, or use the titleId slot property to specify which element should be read out as the dialog title.
Nested Dialog
If a Dialog is nested in another Dialog, append-to-body is required.
Centered content
Dialog's content can be centered.
TIP
The content of Dialog is lazily rendered, which means the default slot is not rendered onto the DOM until it is firstly opened. Therefore, if you need to perform a DOM manipulation or access a component using ref, do it in the open event callback.
Align Center dialog
Open dialog from the center of the screen.
Destroy on Close
When this is feature is enabled, the content under default slot will be destroyed with a v-if directive. Enable this when you have perf concerns.
Draggable Dialog
Try to drag the header part.
TIP
When using modal = false, please make sure that append-to-body was set to true, because Dialog was positioned by position: relative, when modal gets removed, Dialog will position itself based on the current position in the DOM, instead of Document.Body, thus the style will be messed up.

FAQ
Using dialog in SFC, the scope style does not take effect.
Typical issue: #10515
PS: Since the dialog is rendered using Teleport, the style of the root node is recommended to be written globally.
When the dialog is displayed and hidden, there is a situation where the page elements are displaced back and forth.
Typical issue: #10481
PS: It is recommended to place the scroll area inside a vue mounted node, e.g. <div id="app" />, and use the overflow: hidden style for the body.
