ORIGINAL QUESTION
=================
I'm looking for examples of tab or tab-like horizontal navigation
systems with more than two levels. I can find plenty of examples of
two-level tab navigations. Here are a few:
<http://macromedia.com/>
<http://www.apple.com/>
<http://www.welie.com/patterns/showPattern.php?patternID=doubletab>

However, I can't find any sites using a third level. Is there a
particular reason for this? Any research or testing available?

A related question is related to the way sublevel contents are
displayed. Apple's site changes the contents of the menu when a new
page reloads, while Macromedia's menu (which requires Flash) shows each
top level's content as you mouse over the top level items. Is one way
better than the other from a usability point of view, and if so, why?

SUMMARY
=======

In short: be careful when you use tab based navigation, and try to keep
it at no more than two levels deep.

REPLIES
=======

Roger,

First of all, what specifically is the navigation for?  You have to be
careful using tab
navigation.  Too many people have 'strayed' and created less usable
systems using this
metaphor.  Are you doing it because Steve Krug said?  Because you think
it looks cool?  Or are
you doing it because it is the most suitable form of navigation for
your user's needs.

Tabs can be wonderful if:
The primary navigation will NEVER change.  Tabs don't scale (just ask
the designers at Amazon
who made the biggest tab faux pas ever a while back by implementing
multiple rows - at one
point it was three rows deep!  Thankfully, they have since corrected
this hideous usability
mistake);
They are used for the correct reason.  The original use of tabs was to
provide different views
of the same information (great for user centred designed sites
providing different views
relating to different goals/roles).  These days, it has been
bastardised for so long by
indescriminate web design, that it's an accepted population stereotype
to use tabs as the
primary navigation of an IA.  Make sure that the naming convention is
consistent if you are
going to use this bastardisation (all verbs, or all nouns is usually
best).
They look like tabs.  Many sites employ what may, or may not be tabs.
Make them visually
obvious e.g. Apple.com

<http://www.welie.com/patterns/showPattern.php?patternID=doubletab>
These don't have 2 level tab navigation.  The tabs are the primary
navigation, the secondary
navigation are the categories below - usually in a related colour.  2
level tab navigation is
one of the largest usability mistakes that Microsoft made in designing
overbloated
options/preferences boxes.

However, I can't find any sites using a third level. Is there a
particular reason for this? Any research or testing available?
Wow - it must be a HUGE site, or perhaps the IA requires a re-think?
Sites as large and
diverse as Amazon.com only go down to secondary navigation.  However,
if you feel that
tertiary navigation is really necessary, it is usually presented as
left-hand navigation.

A related question is related to the way sublevel contents are
displayed. Apple's site changes the contents of the menu when a new
page reloads, while Macromedia's menu (which requires Flash) shows each
top level's content as you mouse over the top level items. Is one way
better than the other from a usability point of view, and if so, why?
If you have a good Information Architecture with labels that your
target market can instantly
understand (performed open card sorts and used the results in
subsequent testing), Apple's
format is very usable.

I hope this helps.

I know of one site that uses three levels:

http://www.thinkorswim.com/

Click on "Client Access" or any of those other bottom tab-like
interface elements, and you'll see a third row appear beneath it.

I don't personally think it's very easy to understand, but they
don't seem to get too many complaints about it (I did some tech
support for them a while back).

Roger,

The reason that there is no third level and that "stacked" navigation
is not used very often is because it is difficult for users to
understand what navigation matches what "tab". http://www.fool.com/
uses it too and our favourite friends www.amazon.com use it too. In
tests that I have run users have an extremely hard time with this tab
metaphor. In paper-prototype testing tab metaphors are almost
impossible, only coloured visual distinction makes a difference.

They have an even harder time with another 3rd layer. I have had visual
designers change my page layout before and kill the usability of my
navigation by "stacking" to save space.

To sum it up:
Tabs are great when the visual distinction is clear but tests badly in
black and white
Horizontal navigation does not allow for much growth, i.e. not flexible
A 3rd layer is murder on usability b/c users cannot quickly understand
what navigation goes with what, just try it and see what it looks like.

Just for final proof:
Amazon tried this a few years ago in a test and it failed miserably.

Please don't stack navigation any more than you have to. I'd hate to
use the site that does.

Good luck. If you don't believe me, test it yourself.

cheers

Roger,

www.etrade.com uses a triple-tiered tab system with some nice
javascript that I personally find quite interesting. It is a financial
site so you might have to chose to open an account to visit ;-)

Hello Roger,
... A related question is related to the way sublevel contents are
displayed. Apple's site changes the contents of the menu when a new page
reloads, while Macromedia's menu (which requires Flash) shows each top
level's content as you mouse over the top level items. Is one way better
than the other from a usability point of view, and if so, why?...


We have found that requiring flash for a main navigation element will
limit
the audience and could potentially slow down the page.  I wrote an
article
earlier this year specifically on the Tab control as implemented in a
visual
design pattern. This article is available on our site and offers free
code
and graphic templates:
http://www.classicsys.com/classic_site/articles/articles_1-03.html

Good luck.

Jim Hobart
