1309941 - The ContentSelectDropdown popup should open with the selected item appearing on top of the 'select' element

Status: RESOLVED DUPLICATE of bug 430745

(Core :: Layout: Form Controls, defect)

Description

[Jared Wein [:jaws] (please needinfo? me)]

Right now the popup appears either above or below the <select> element, regardless of which is the selected option.

When the menu is opened, the menu appears like so (animation from left to right), with a list of fruits that has Apple selected:

[ Apple |v]
            [ Orange ]
            [-Apple--]
            [ Banana ]

We should position the popup so that the option that was selected prior to opening appears on top of the select group-button.

[ Apple |v]

When the menu is opened, the menu should appear like so (animation from left to right):

            [ Orange ]
[ Apple |v] [-Apple--]
            [ Banana ]

(where -- means that the item is selected)

What you suggest is clearly the wrong behavior on Windows and GTK.
But yes, we do want that behavior on OSX.

I think it is a stretch to say this is "clearly wrong behavior on Windows". More discussion here may be necessary as Edge now does this same behavior on Windows, so this would match Edge-compat there.

Interesting, I wasn't aware Edge was doing it this way.  Fair enough,
we might want to do this on Windows too then.

My point is, there's a fair amount of platform specific behavior in form
controls that we (until now at least) have considered important enough
to implement, to avoid alienating users who often have an expectation
of those behaviors in their "muscle memory".  Have our reasoning about
this changed recently?  I haven't seen any discussion on m.d.platform
or elsewhere about it.  I certainly think it's a major change that
should be discussed more widely if we're going to ditch that approach
and implement a "common denominator" behavior across platforms.

Hey Philipp / Stephen,

Can you comment here as to if we should make this change for Windows? Bug 430745 is already on file for doing this on OSX, which is where we could do the work for now and expand it to Windows if we feel that it is a good fit there as well.
