Form layouts
Be sure to read the full forms usage guidelines.
Form and form rows
Use the EuiFormRow component to easily associate form components with labels, help text, and error text.
Use the EuiForm component to group EuiFormRows. By default EuiForm will render as a simple div unless
you pass component="form".
Full-width
Form elements will automatically flex to a max-width of 400px. You can optionally pass the fullWidth prop
to the row and form control to expand to their container. This should be done rarely and usually you will only
need it for isolated controls like search bars and sliders.
Global full-width
To set all the row and controls in a form to fullWidth, specify the prop on the root EuiForm component.
Inline
Inline forms can be made with EuiFlexGroup. Apply grow={false} on any of the items you want
to collapse (like the button below). Note that the button's EuiFormRow wrapper also requires an additional prop
when it’s missing a label hasEmptyLabelSpace.
Sizing inline form rows
Apply a width or change the grow prop on the wrapping EuiFlexItem to size individual controls.
When you need to make a field smaller, always apply the width to the flex item, not the input.
The input inside will resize as needed.
When supplying children to an EuiFormRow that is not a form control, and you need to the content
to vertically center with the other form controls, change the display prop to center or centerCompressed.
Described form groups
Use EuiDescribedFormGroup component to create sections of associated form controls and rows. It can also simply be used with one EuiFormRow as a way to display additional text next to the field (on mobile, it will revert to being stacked).
Read more about appropriate layout usage of EuiDescribedFormGroup in the forms usage guidelines.
Sizing described form rows
By default, EuiDescribedFormGroup has a max-width of 800px for best readability.
To expand the group to 100%, add the fullWidth prop to this, the EuiFormRow, and the individual fields.
You can also change the ratio of the width of the description column versus the field column.
By default, it is 'half', but you can also change to 'third' or 'quarter' which prioritizes the field column.
You will most likely still need to apply fullWidth to all the components. The description column does have
a minimum readable width applied to it so that it cannot shrink too far.
Both the description and field columns are simply EuiFlexItem wrappers. If you need more customization
of these columns you can pass flex item props to descriptionFlexItemProps and fieldFlexItemProps respectively.
Form labels
The best way to provide an accessible name to form elements
is to use the label prop provided by EuiFormRow. However, certain types of form controls require extra care
to ensure an accessible experience. Below are just a few examples.
Form controls that come with their own label don‘t need the one provided by EuiFormRow.
For controls like EuiSwitch, EuiButton, and EuiLink be sure to pass hasChildLabel={false}
to the wrapping EuiFormRow.
Implicit titles for the first form control
When displaying the form control's name in some other way than through the visual label prop,
the form control still needs to be associated with that element. To do this, either:
- duplicate the text and pass it as the
aria-labelof the form control, or - pass the
idof the text to the form control'saria-labelledby.
More complicated form labels
Some controls are just hard though and will often require some custom work. Refer to an individual component‘s documentation and remember to test with a screen reader!
In a popover
Because forms auto-size to their wrapping elements, it means you can do fun things with them like stuff them in popovers, and they’ll still work perfectly.
