This template has the Smart Search Panel Status. It means, system will save the last status of Search Panel; whether collapsed or expanded.
In this demo, make sure you have already logged in, and then try to play with Search Panel in Orders (or the other) List page.
In that List page, just click on Search Panel to expand it (if the current status is now collapsed), then browse to another page. You will see that last status (expanded) will be remembered and this status will be loaded in future.
This is very useful if you want to collapse the Search Panel while browsing to next page.
