Navigation submenus – what’s the best approach? Dropdown, hovers, clicks or keeping it flat?

/ Commentary

I agree with this post from Mark Root-Wiley which argues that dropdown navigation menus are best activiated when a user clicks the link (or, correctly speaking, button) rather than hovers over it. Adrian Roselli also writes really well on how to implement this UI pattern accessibly.

Adrian Roselli’s navigation menu item is clearly styled as a button that should be clicked, complete with animated caret control.

This came up at work recently, where the hover pattern has been implemented on an extranet. I predict it will cause problems for the normal reasons – affordability, dexterity and annoyance – especially considering the age of the audience using the website. Any testing, or even your own day-to-day experience, will demonstrate how frustrating it is to hover over a link to reveal a submenu, and then avoid accidentally triggering dropdowns.

But whether you’re using a click or hover pattern, you’re still creating a new set of problems whenever you implement any dropdown menu. That is, what’s the top level link/button text for?

Take Adrian’s menu. It asks two questions:

  • Can I click the “Blog” text? Is it a link to somewhere else or just a button label?
  • If it does serve as a link to a page, what should appear on that page if all the subpages are listed when you click the button?

Adrian opts to makes it a link to the website home page, which I feel is confusing as it’s labelled “Blog”, even if Adrian’s site is a blog. It’s also a fairly complicated set of controls to negotiate – a link/label next to a disclosure widget.

This lead me to follow Heydon Pickering’s advice on accessible menu systems when we developed the work site last year:

Where a site has a lot of content, a carefully constructed information architecture, expressed through the liberal use of tables of content “menus” is infinitely preferable to a precarious and unwieldy dropdown system. Not only is it easier to make responsive, and requires less code to do so, but it makes things clearer: where dropdown systems hide structure away, tables of content lay it bare.

The top level menu is eniterly flat. In the spirit of not hiding content behind disclosure widgets, you’ll also see as many navigation items as your screen’s width will allow:

No dropdowns or hamburgers. Note the main content consists of a menu of common tasks.

Feedback and testing have revealed no problems with this approach – it appears users are happy to delve into tables of content several levels deep, as long as the trail is clear enough.

However, I can see possible benefits in implementing dropdown menus well:

  • Increased discoverability of website subsections
  • Confirmation of what a website section contains, without having to click through to that section
  • Efficiency for users familiar with the navigation menu, where dropdowns serve as a shortcut to the content they’re interested in

I am, on the whole, very happy with using a flat, signposting system for website navigation, but what do you think? Do you see a use for dropdowns in some circumstances?
