[pve-devel] [PATCH manager v4 07/10] ui: add form/Tag

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

displays a single tag, with the ability to edit inline on click. This brings
up a list of globally available tags for simple selection.

Also has a mode for adding a new Tag.

This has a 'updateCallback' which is called when the value changes
so that the parent component can update the config, and a
'layoutCallback' which will be called on input, so that the parent
component can update the layout when the content changes.
This is necessary since we circumvent the extjs logic for updating.
