Usage

Disabled

Read Only

Required

If you pass the isRequired property to the input, it will have a danger asterisk at the end of the label and the input will be required.

Sizes

Colors

Variants

Radius

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, the labelPlacement property will be outside 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: HeroUI Input also supports native events like onChange, 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 and maxLength specify the minimum and length of text input.
• pattern provides a custom regular expression that a text input must conform to.
• type="email" and type="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. HeroUI 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.
