Show · SideSheet
An overlay panel that slides out from the edge of the screen, typically used to host secondary action pages.


How to import

Basic Usage

By default, SideSheet slides from the right side of the screen and could be closed by clicking on the mask.


You could use placement to set the position from which SideSheet comes in, supporting one of top, bottom, left, right


You could use size to set the size of SideSheet, supporting one of small(448px), medium(684px), and large(920px). Only takes effects when placement is set to left or right, and used after v0.29.0. If the default size does not meet your needs, you can also set the width by setting the width property, for example width={900} / width={'800px'}

Non-blocking Workflow

After v0.29.0, you could set mask={false} to continue working on the area outside SideSheet.
By default, if you are not setting `getPopupContainer`, SideSheet is rendered inside body. If you want body element to be able to scroll, you could set disableScroll to false and the component will not add `overflow: hidden` to it.

Rendered Inside Container

After v0.29.0, you could use getPopupContainer to render SideSheet in targeted DOM.
The container must have `overflow: hidden` to avoid animated SideSheet overflows.

Customized Content

Use title, footer(v>=1.3.0) and other Semi Components, you could create customized information display layers.

  • SideSheet has a dialog role to indicate that it is a pop-up component, and the internal header has a heading role to indicate that it is a header.
