How to set left sidebar is minimized as default

Hi all,
I want to show left sidebar minimized as default. I have tried to add minimized props to `AppSidebar` element as bellow `<AppSidebar fixed minimized>`. When i reload page i see it looks good but when i hover the mouse on it, it doesn't show child's menu level.
 It's behavior isn't the same when i click on  `AppSidebarMinimizer` element two times (that way works perfectly)

Thank all.
