A Label provides a descriptive title for a form input. Having labels is essential when filling out a form, since each field is associated with its label.


Using labels

The Label component will be placed above each form Field. An optional indicator, a tooltip, and a description could also be included next to the label text.

Example of Codex Label being used within a Codex Field.


Specification of Label.

The Label may include the following elements:

  1. Icon (optional)
    A start icon can be included to visually enhance the label's context. This icon is fully customizable and any icon from the provided list can be used. Use a simple icon that is easily comprehensible to users.
  2. Label text
    A clear and descriptive title for the form field that tells the user what information to enter.
  3. Field indicator (optional)
    Subtle text indicating that the field associated with the label is not required.
  4. Description (optional)
    Subtle descriptive text that provides additional information about the field.

Label is used within Field. It can also be used on its own for cases when the Field component cannot or should not be used (e.g. to label a SearchInput).

Refer to the Label component in Codex Figma.

Interaction states

Label includes only two states:

Interaction states of Label: default and disabled.

  1. Default
  2. Disabled



You should consider using the Field component, which includes the Label component and handles accessibility features like ARIA attributes internally. If you need more custom behavior, you can use the Label component on its own.

Note: For icon properties, the relevant icon also needs to be imported from the @wikimedia/codex-icons package. See the usage documentation for more information.

Basic usage

When using the Label component with an input, make sure to add an id attribute to the input and use that to set the for attribute on the label. These attributes will be applied on the proper element within each component (in the example below, that's the <label> for the Label component, and the <input> for the TextInput).

Visually-hidden label

In rare instances, you may not need a visible label if it's very clear from context how to use an input. To achieve this, you can use the Label component to create a semantic label for assistive technology, but add the visuallyHidden prop to visually hide the label.

Note that this will hide the entire output of the component, including the description.

With rich description text

You can include markup in the description slot. Only links and text formatting are recommended as description text should be concise.

Label vs. legend

This component outputs a <label> element by default. When the isLegend prop is set to true, it will instead output a <legend> element. Use this within a <fieldset> element.

There is a named slot in the Label component, description, for including more information about the field. It's important to note that, when isLegend is true, the description will be rendered inside the <legend> element to ensure it will be read by assistive technology.

Below are examples of a label and a legend with an associated description.

Vue usage


Prop nameDescriptionTypeDefault
iconIcon before the label text.

Do not use this if including a start icon within the input component.
optionalFlagText to indicate that the field is optional.

For example, this might be '(optional)' in English. This text will be placed next to the label text.
visuallyHiddenWhether the label should be visually hidden.booleanfalse
isLegendWhether this component should output a <legend> element.

Always set this to true when this component is used inside a <fieldset> element. Do not set it to true otherwise.
inputIdThe ID of the input/control this label is for.

Will be added as the for attribute of the <label>. Not needed for <legend>.
descriptionIdThe ID of the description element.

This ID can be used for the aria-describedby attribute of the input.
disabledWhether this label is for a disabled field or input.booleanfalse

Markup structure

Examples are shown with inputs to demonstrate the ARIA attributes required to connect the label and input.


Use a <label> element for a single input.

Short description text


Inside a <form>, use a <legend> element within a <fieldset> for input groups.

When outputting a <legend> rather than a <label>, the markup of this component is quite different:

  • There is no wrapper <div><legend> must be a direct child of <fieldset>
  • The description is included inside the <legend>
  • The for and aria-describedby attributes are not needed
Legend text (optional) Short description text

With icon

To add an icon to the label:

  • Add an empty <span> before the label text with the classes .cdx-label__label__icon and a custom class that you can target to add the CSS-only icon
  • Apply the CSS-only icon mixin to that <span>

This works for <label> and <legend>.

Visually hidden

Occasionally, there may be a use case for the label to be visually hidden. In these cases, it should still be present in the DOM with appropriate elements and ARIA attributes.

To visually hide the label, add the .cdx-label--visually-hidden class to the outer element. This works for <label> and <legend>.


Add the .cdx-label--disabled class to the outer element to get disabled styles. This works for <label> and <legend>.
