React Form Input Component

Form control

React input components. Give textual form `<input>`s an upgrade with custom styles, sizing, focus states, validation, and more.

Other frameworks

CoreUI components are available as native Angular, Bootstrap (Vanilla JS), and Vue components. To learn more please visit the following pages.

On this page

Example#

<CForm>
  <CFormInput
    type="email"
    id="exampleFormControlInput1"
    label="Email address"
    placeholder="[email protected]"
    text="Must be 8-20 characters long."
    aria-describedby="exampleFormControlInputHelpInline"
  />
</CForm>

If you need to add custom classNames to form's components, or need to add some custom elements you can add each form component separately. Please check the example below.

<CForm>
  <CFormLabel htmlFor="exampleFormControlInput1">Email address</CFormLabel>
  <CFormInput type="email" id="exampleFormControlInput1" placeholder="[email protected]" aria-describedby="exampleFormControlInputHelpInline" />
  <CFormText as="span" id="exampleFormControlInputHelpInline">
    Must be 8-20 characters long.
  </CFormText>
</CForm>

Sizing#

Set heights using size property like size="lg" and size="sm".

<CFormInput type="text" size="lg" placeholder="Large input" aria-label="lg input example"/>
<CFormInput type="text" placeholder="Default input" aria-label="default input example"/>
<CFormInput type="text" size="sm" placeholder="Small input" aria-label="sm input example"/>

Disabled#

Add the disabled boolean attribute on an input to give it a grayed out appearance and remove pointer events.

<CFormInput type="text" placeholder="Disabled input" aria-label="Disabled input example" disabled/>
<CFormInput type="text" placeholder="Disabled readonly input" aria-label="Disabled input example" disabled readOnly/>

Readonly#

Add the readOnly boolean attribute on an input to prevent modification of the input's value. Read-only inputs appear lighter (just like disabled inputs), but retain the standard cursor.

<CFormInput
  type="text"
  placeholder="Readonly input here..."
  aria-label="readonly input example"
  readOnly
/>

Readonly plain text#

If you want to have <input readonly> elements in your form styled as plain text, use the plainText boolean property to remove the default form field styling and preserve the correct margin and padding.

Password

<CRow className="mb-3">
  <CFormLabel htmlFor="staticEmail" className="col-sm-2 col-form-label">Email</CFormLabel>
  <CCol sm={10}>
    <CFormInput type="text" id="staticEmail" defaultValue="[email protected]" readOnly plainText/>
  </CCol>
</CRow>
<CRow className="mb-3">
  <CFormLabel htmlFor="inputPassword" className="col-sm-2 col-form-label">Password</CFormLabel>
  <CCol sm={10}>
    <CFormInput type="password" id="inputPassword"/>
  </CCol>
</CRow>

<CForm className="row g-3">
  <CCol xs="auto">
    <CFormLabel htmlFor="staticEmail2" className="visually-hidden">
      Email
    </CFormLabel>
    <CFormInput type="text" id="staticEmail2" defaultValue="[email protected]" readOnly plainText />
  </CCol>
  <CCol xs="auto">
    <CFormLabel htmlFor="inputPassword2" className="visually-hidden">
      Password
    </CFormLabel>
    <CFormInput type="password" id="inputPassword2" placeholder="Password" />

  <CCol xs="auto">

      Confirm identity
    </CButton>
  </CCol>
</CForm>
