Label Placements
You can change the position of the label by setting the labelPlacement
property to inside
, outside
or outside-left
.
Note: If the
label
is not passed, thelabelPlacement
property will beoutside
by default.
Password Input
You can use the type
property to change the input type to password
.
Clear Button
If you pass the isClearable
property to the input, it will have a clear button at the
end of the input, it will be visible when the input has a value.
Start & End Content
You can use the startContent
and endContent
properties to add content to the start and end of the input.
With Description
You can add a description to the input by passing the description
property.
With Error Message
You can combine the isInvalid
and errorMessage
properties to show an invalid input. errorMessage
is only shown when isInvalid
is set to true
.
Example with regex
email validation:
Controlled
You can use the value
and onValueChange
properties to control the input value.
Note: NextUI
Input
also supports native events likeonChange
, useful for form libraries such as Formik and React Hook Form.
With Form
Input
can be used with a Form
component to leverage form state management. By default, Form
components use validationBehavior="aria"
, which will not block form submission if any inputs are invalid. For more on form and validation behaviors, see the Forms guide.
Built-in Validation
Input
supports the following native HTML constraints:
isRequired
indicates that a field must have a value before the form can be submitted.minLength
andmaxLength
specify the minimum and length of text input.pattern
provides a custom regular expression that a text input must conform to.type="email"
andtype="url"
provide built-in validation for email addresses and URLs.
When using native validation, error messages can be customized by passing a function to errorMessage
and checking the ValidityState of validationDetails
.
Custom Validation
In addition to built-in constraints, you can provide a function to the validate
property for custom validation.
Realtime Validation
If you want to display validation errors while the user is typing, you can control the field value and use the isInvalid
prop along with the errorMessage
prop.
Server Validation
Client-side validation provides immediate feedback, but you should also validate data on the server to ensure accuracy and security.
NextUI allows you to display server-side validation errors by using the validationErrors
prop in the Form
component.
This prop should be an object where each key is the field name
and the value is the error message.
