如何使用JS，Telerik和Kendo UI动态启用数据标记

我正在使用Telerik的App Builder和Kendo UI来尝试构建SPA应用程序。我对使用Telerik和Kendo UI很陌生，请原谅代码。我正在努力完成两件事。

1. 启用滑动以打开和隐藏登录头像，直到用户登录。
2. 当用户注销后，返回登录屏幕并禁用滑动以打开和隐藏登录标题图像。

我尝试在布局中添加：数据滑动打开="false"，使用布局标题上的 .hide。当我使用数据滑动打开="false"时，#appDrawer 不会打开（这是我想要的），但我无法设置数据滑动打开= true。 我找不到来自 Telerik 的任何文档。

感谢任何和所有反馈。

截至目前的登录屏幕

登录时滑动
