How can I keep only one child opened at a time for multiple levels dropdown

[anhcunmio]

I see the showOneChild prop on the document but it works for the first level only.

Is there a way to close all siblings when clicking the sub-menu?

Thanks

Currently only the first level is supported

Added 'deep' support in v5.4.0.

<sidebar-menu :show-one-child="'deep'" />
