If all the attached examples are orderless, why do 3 of them have the
+
button on every row?
+1. it seems that all widgets should contain the "+" button only in the
last row.
I think it will be a good idea to lock down the behavior for ordered
and
order-less rows as Einav mentioned for consistency.
assuming everyone are OK with adjusting all existing widgets (which are
all orderless, as was mentioned here) so that they will contain the "+"
button only in the last row, then we currently don't even need to
introduce the "ordered" flavor to AddRemoveRowWidget.
I understand that the row content can be different based on the use
case but we need to have some basic commonalities - For e.g, in the
VNic Profile example, we should have a label for the first text
field as it is not really clear what that starting empty text field
is for - I can deduce it is for the Profile name but can't be sure.
+1. We should think of a consistent way of "labeling" the different
parts within a row / provide an explanation for a row (for all of the
row types that we currently have).
Today there is a bit of a mess: In the vNIC assignment, there is a top
explanation of "VM has x network interfaces. Assign profiles to them".
In vNIC profiles, there isn't a top explanation, but the check-box and
drop-down are labeled, however the text-box, as you mentioned, is not.
In the Profiles/Custom-Properties, there are no explanations and no
labels at all.
