The Kendo UI for Angular team created a forms guide to not only be the hippest kids on the block, but to also help developers with something that is so common and yet often could be done better. Our forms guidance comes from years of creating forms, working with partners on their forms, and always struggling to meet all accessible and SEO needs that arise in such an area.
Our forms guide covers a wide range of topics, from how to structure a horizontal form with labels inline instead of the default stacked one, how to separate form components into logical chunks, the best way to handle hint and validation messages, displaying content in a form based on the state of a form element and so much more. We gathered all this information to help you create the best possible Angular forms possible, even if you're not using Kendo UI for Angular. I’ll dive into a few of the juiciest 💦 pieces of advice in this article. Be sure to check out the full Forms Guide to see our full list of advice when it comes to semantic and well behaved forms!
A common way to create forms and display labels is vertically, like the form below. This is created by having the labels and inputs be block level and full width, so they all stack nicely in a column. (This is default, btw, with Kendo UI form components inside a parent
However, it is a simple matter to have side-by-side or inline labels for a “Horizontal Layout”:
k-form-horizontalclass to the

A good tip to remember for SEO and accessibility wins is to group your form controls logically and surround groups with
A legend is a way to create a label for a group of content (the fieldset).
Sometimes it can be hard to know when we should use elements like this in our forms. The accessibility blog for Gov.UK advises to use them whenever you have multiple questions relating to the same topic or a multiple choice question with radio buttons that need to be grouped together under one legend.
When used correctly, the fieldset and legend elements tie related form fields together in a way that is accessible to people who cannot see the visual layout of the form. — Gov.UK
SEO and Accessibility are two items that people do not always think about for Forms, but one solution to furthering your form towards a more being more accessible is utilizing these two elements.
Another super simple and under-used solution for chunking forms is the line break!
Separators add a line break to the layout and improve the form conversion rate. The separation of sections allows you to make long forms easier to handle. To add a separator, add the
k-form-separatorclass on a
Just look at how such a small thing can really elevate a form:
It’s such a small thing but it can really help break up content and set a smoother flow for the user. Using Kendo UI, it is as simple as adding a
Another issue our forms guide gets into is form validation. It’s important to give feedback to users when they’re walking through a form. Not just the color indicators of the form-field or the error messages are important, but also the timing of the error. It’s best to have the errors only show up after the field has been touched or edited (
It’s important to not only have validation on your forms, but have it occur at the right time. Right after the user has improperly filled something out is the time to alert them, not when the form is being submitted.
Kendo UI’s FormField component enables you to control when and how validation messages will be shown, easily, in compliance with the Angular form validation guide. Check out more on the FormField component in our docs for more details.
Along with the accessibility guidelines, logical form chunking and form validation, our forms guide also outlines many of our commonly used form elements and how to construct them together properly in an Angular form. Check it out for all your form needs: Forms Guide.
