About improve implement of some components

[100cm]

According to my experience of AT UI For Angular.

Now the implement of some components such as dropdown, select, and other components which will add overlay document to the window have some problem , like can't auto change position (when the window scrolled or resize the window, i don't know if will have low performance problem in Vue) , so you should better have a component/directive that render the overlay document , connect the origin trigger document and the overlay document by [slot].

Element UI have done this well.

for example

And At UI for Angular

Thanks you again for providing AT UI.
