Extjs: The menu is automatically hidden after the mouse is removed from the menu.

1. extjs2.0.2 is used.

2. The problems encountered are briefly described as follows:

When the drop-down menu is displayed, if you move the mouse away without any operation, the menu will not disappear (hide) automatically and will always be displayed on the screen.

You must click a menu item or click somewhere else on the page to hide the menu ).

3. In order to enhance the user experience, after removing the mouse from the drop-down menu, the menu can be automatically hidden.

Below is the test demoCode:
