10 best practices for mobile form design

if_seo_web-46_1046182.pngUX Matters had this interesting article on mobile form design. At frevvo, we’ve created thousands of forms and workflows for mobile devicesand we’ve learned a lot along the way. One thing is absolutely true:

“As technology continues to go through metamorphoses and our understanding of users’ needs becomes more refined, good mobile form design is constantly evolving.”
– Quoted from above article

Getting your forms to be genuinely usable on mobile devices is hard but can have big benefits. Fortunately, with frevvo, you don’t have to worry too much about this. Let’s take a look at a few things mentioned in the above excellent article:

1. Use a single input field where possible

It’s all well and good to say create a single input field called Name but if the form integrates with your CRM or some other back end system, maybe a First and Last name are required. With frevvo, you have all the flexibility in the world. Display a single field on the form called Full Name and use a business rule to split it into First and Last name hidden fields if that’s what you need. There’s going to be some guesswork to split it accurately but you can automatically get it right most of the time. Serve the needs of your marketing team and your users at the same time.

2. Create a conversational flow

if_seo_web_2-43_1045323.pngAs Justin Mifsud pointed out back in 2011, “A form is a conversation, not an interrogation.” The flow of information in the form should have a conversational feel. Usually, this means split the form up into multiple pages that feel natural. But, you have to consider differences between mobile and desktop forms. What might be natural on a phone with its limited screen real estate doesn’t make sense on the desktop and could be irritating – why do I have to walk through so many steps?

Fortunately, frevvo makes it easy. Simply drag in Page Break controls and mark them smart phone only. On a desktop or tablet with lots of screen real estate, you’ll see the whole form (or Section or Tab). On the phone, it’s broken up into multiple pages with automatic Next and Previous buttons.

3. Automatically pre-fill values in fields

No explanation necessary – the less stuff users have to fill in the better off you are. This is one of frevvo’s strongest suits. You can pre-fill information from any number of sources. For example, check out this example that fills out Customer information from a SQL database. Another common example: if the user is logged in, you can automatically fill in their personal information. It eliminates errors, reduces typing and is far less frustrating for users.

For mobile users, frevvo supports functionality like GPS integration. You can use the GPS device on the phone to pre-fill an address field or figure out the location of the closest physical store and display it on the form.

4. Make forms accessible

From the UX Matters article: Of the people who have disabilities, 91% use a mobile device, according to a 2013 study (PDF) by the Wireless Rehabilitation Engineering Research Center. Wow! I had no idea. Technology, especially mobile technology is making the world more and more accessible to people with disabilities but only with accessible mobile design.

Fortunately, with frevvo, accessible design is just built-in. Our forms and workflows have been accessible (satisfying WCAG guidelines) for years. Government organizations worldwide have legal requirements to provide accessible forms and many are already using frevvo for their constituents.

5. Break up lengthy forms into steps or stages

if_seo_web-48_1046184.pngThis is very connected to #2 above. With frevvo, breaking up lengthy forms into steps is a piece of cake. What’s best is that you can design your form once and set it up so that it’s broken up into steps on a phone with automatically generated Next and Back buttons. On the desktop with its abundant real estate, you can simply show the entire form or break it up into fewer steps. Again, satisfy the needs of your users with a natural user experience no matter where you are.

You can also create multi-step flows in frevvo (we call them screen flows) that explicitly walk you through multiple steps on all devices with a progress bar / nav bar at the top etc. It’s totally up to you.

6. Create minimal forms, but ask the essential questions.

rb-03This is a particularly crucial aspect of form design. Obviously, in frevvo, you can create as minimal a form as you want. One of the most effective things we’ve found is context-sensitive show/hide. It’s easy with frevvo using simple, visually-built business rules. In any form that’s displayed, hide away unnecessary fields until they’re actually “essential”. For example, on an Employment Eligibility Verification form, some questions may only be applicable to non-citizens. Hide them away until the user selects the “I’m not a citizen” option.

You’ll find that users are less confused and more likely to complete and submit your form if the screen is less cluttered. It seems obvious and fortunately, with frevvo, it’s also a piece of cake.

7. Display mobile-friendly error messages.


This is yet another crucial aspects of good UX. IMHO, this is applicable on all devices not just mobile. We’ve seen so many instances of forms where you fill it out, submit, the server thinks for a while and reloads the page with errors. The errors may be displayed at the top far away from the fields. It’s a nightmare.

With frevvo, user-friendly error handling has always been a priority. Validation of controls is instant and usually automatic. If there’s an error, the user will know immediately. The control visibly changes (color/icon) and an error message appears right below the control. You can customize this message to be meaningful to the user and it can even be configured dynamically so that it tells the user precisely what went wrong.

With frevvo, you also cannot submit invalid forms. If required controls aren’t filled in or there are errors and a user still clicks Submit, the form will automatically highlight the errors/missing data. If you want, you can also display one or more custom messages right above the Submit button that was clicked so the user knows that something went wrong.

The thing you want to avoid is “Oops! An error occurred. Please try later.” Nothing’s more frustrating for users. Fortunately, with frevvo mobile [and other] user friendly error handling is automatic and built-in.

8. Avoid using drop-down menus and lists.

It’s true. Long drop down menus/lists are not very user friendly on mobile. Where they can’t be avoided, frevvo does provide a natural mobile friendly experience. For shorter lists, we definitely prefer radio buttons. With frevvo, it’s easy to lay them out so that if two or more fit on a single row, they’ll be laid out side by side and consume less real estate.

frevvo also offers an auto-complete Combo box though we’ve found that it’s not necessarily a better experience on mobile than a pick list. The good news is you can choose whichever control makes sense for your needs.

9. Bigger buttons, radios etc.

One of the other things we’ve learned is that it’s genuinely harder to click things with your fingers on mobile. Therefore, in spite of the reduced real estate, frevvo’s controls are subtly larger, buttons are just a bit bigger, radios are easier to click on etc.

10. Responsive forms

LandscapeWhen fonts are too small to read or the screen looks cramped, what will many users do? Rotate the device to landscape mode so there’s more horizontal real estate. Nothing’s more frustrating and annoying than to see the same size form with the same fonts displayed on the landscape screen – even Google and Amazon do it.

With frevvo, all this is just automatic. From big wide desktop screens to small smart phones, your forms will automatically adjust. Rotate your device – the form will expand to take up all available space. Zero CSS3 or HTML5 or any code. It just works.

11. BONUS – Good looks

Let’s face it. People are more likely to use UIs that look good. Forms aren’t the world’s sexiest user interface but they are ubiquitous. Might as well make them look great. With frevvo, that’s also automatic 🙂 Do nothing and your forms will just look good on all devices. And there are many little bits of eye candy such as decorators – add little meaningful icons to your controls e.g. an envelope for an Email field or a map marker for a Zip Code. Styles let you customize colors so your forms fit into your brand and website. These are little things but they can make a huge difference.

Mobile is everywhere and forms are everywhere. You probably have mobile users filling out forms and participating in workflows in your organization. With frevvo, make them mobile friendly without the need to spend significant resources and money.




Embed frevvo on mobile pages

mobiledevicesfrevvo’s forms and workflows already work well on mobile devices. They’ll automatically resize to fit your phone or tablet, the icons and controls will be slightly larger, long forms can be broken up into multiple pages etc. They just work without much tinkering if any.

But, customers want to embed them in their mobile web pages. Since the web page and form are usually served up from different hosts, we have to use an iframe. And iframes are notoriously difficult on mobile devices. It’s doubly tricky for us since the size of the form can change e.g. when the user selects a different Tab or expands/collapses a Section or clicks + to add a repeating item.

This slideshow requires JavaScript.

Fortunately, mobile browsers & devices have now evolved to where we can provide this to customers. As you can see from the slideshow above, frevvo’s own Contact form is embedded in our website and renders perfectly in an iframe on tablets and phones. The forms will resize automatically to the device width, they height will automatically increase if the form height changes (switch Tab, expand Section etc.) and device rotation will also work automatically. We’ll be rolling this out in the next few weeks and customers won’t have to do anything.

We’re also working on rolling out truly responsive forms on desktop browsers since we finally have no customers still using [the much-hated] IE8 and almost no one using IE9 either. But, that’s for another article.
