Collapse

The content area is contained by the collapsed panel

Multiple panels can be expanded at the same time, with no effect between panels

Demo
Consistent with real life: consistent with real-life processes, logic, follow the user's habits of language and concepts;
Consistent in the interface: All elements and structures need to be consistent, such as design styles, icons and text, the location of elements, and so on.
Control feedback: through the interface style and interactive effect so that users can clearly perceive their own actions;
Page feedback: After the operation, the current state is clearly represented by changes in the page elements.
Simplify the process: design simple and intuitive operating process;
Clear and clear: clear language and clear expression, so that users quickly understand and then make decisions;
Help users identify: The interface is straightforward, allowing users to quickly identify rather than recall, reducing the user's memory burden.
User decision-making: according to the scene can give the user action advice or security tips, but can not replace the user to make decisions;
Results controllable: Users are free to perform actions, including undoing, falling back, and terminating the current operation.

Only one panel can be expanded at a time

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.
