UMG / UI Focus Problem

Hello,
I am currently designing UI and trying to incorporate focus for gamepad/keyboard.

In the main menu, I got three displaying user widgets. Using Switcher, it displays accordingly.

When this main menu gets the event On Focus Recevied, I put the following nodes to send the focus to the active widget the switcher is displaying at the moment.

However, my displaying user widgets are designed in border → Switcher->user widget or border.
The following is an example:

When the focus is sent to this widget, the “Content border” gets the focus, since it wraps up all the following widgets. However, since border is not focusable, Unreal sends error message.

Is there a proper way to deal with the focus and switcher? or Does my designing hierarchy need changes?

Thanks for the help in advance!
