[pve-devel] [PATCH manager 1/2] ui: form: add DescriptionFieldContainer

[Dominik Csapak <d.csapak@proxmox.com>]

this is a field container, showing a field on the left column and a
description on the right one, with a (default) flex ratio of 1:2

this is helpful when wanting a longer description on the right column
but still have the fields aligned.

alternatively, we could make a more generic '2column' container, where
we give a 'leftFieldConfig' and a 'rightFieldConfig', and just
let the user put in a displayfield on the right?

would be the more generic solution that could also work when we don't
want to have a description in the right column
