Drawer

Sometimes, the Dialog component does not meet our needs. For example, your form is very long, or you need to temporarily display some documents. Drawer has almost the same API as Dialog, which brings a different experience to the UI.

Call out a temporary sidebar that can be called out from multiple directions

Demo

By setting the IsBackdrop property to true, the drawer is automatically closed when the mask part is clicked

Seems like the connection with the server has been lost. It can be due to poor or broken network. Please hang on while we're trying to reconnect...
Oh snap! Failed to reconnect with the server. This is typically caused by a longer network outage, or if the server has been taken down. You can try to reconnect, but if that does not work, you need to reload the page.
Oh man! The server rejected the attempt to reconnect. The only option now is to reload the page, but be prepared that it won't work, since this is typically caused by a failure on the server.
