Text input

Text inputs are used for inputting single line text data.

Examples

Base

Label

Web Component
HTML Blueprint

<div class="chi-form__item">
  <chi-label for="example__base">Label</chi-label>
  <chi-text-input id="example__base"></chi-text-input>
</div>

<div class="chi-form__item">
  <label class="chi-label" for="example__base">Label</label>
  <input type="text" class="chi-input" id="example__base">
</div>

Disabled

Use the disabled boolean attribute to prevent users from interacting with an input. Disabled inputs are not submitted with the form and can not receive any browsing events such as mouse clicks or focus. Note: The required attribute can not be used on inputs with a disabled attribute specified.

<div class="chi-form__item">
  <chi-label for="example__disabled">Label</chi-label>
  <chi-text-input id="example__disabled" value="Sample Text" disabled></chi-text-input>
</div>

<div class="chi-form__item">
  <label class="chi-label" for="example__disabled">Label</label>
  <input type="text" class="chi-input" id="example__disabled" value="Sample Text" disabled>
</div>

Readonly

Use the readonly boolean attribute to prevent users from changing an input value. Unlike disabled inputs, readonly inputs are submitted with the form and can still receive browsing events such as mouse clicks and focus. Note: The required attribute can not be used on inputs with a readonly attribute specified.

  <label class="chi-label" for="example__readonly">Label</label>
  <input type="text" class="chi-input" id="example__readonly" value="Sample Text" readonly>
</div>

Placeholder

Use the placeholder attribute to provide users with an example of the type of data that can be entered into an input. Note: Placeholder text is not persistent and visually disappears when a value is entered.

<div class="chi-form__item">
  <label class="chi-label" for="example__placeholder">Label</label>
  <input type="text" class="chi-input" id="example__placeholder" placeholder="Placeholder">
</div>

Spinner

Use the spinner attribute to let users know when information is saving or loading.

  <chi-label for="example__spinner">Label</chi-label>
  <chi-text-input id="example__spinner" spinner></chi-text-input>

<div class="chi-form__item">
  <label class="chi-label" for="example__spinner">Label</label>
  <div class="chi-input__wrapper">
    <input type="text" class="chi-input" id="example__spinner">
    <svg class="chi-spinner -icon--muted" viewBox="0 0 66 66">
      <title>Loading</title>
      <circle class="path" cx="33" cy="33" r="30" fill="none" stroke-width="6"></circle>
    </svg>
  </div>
</div>

Required

Use the required boolean attribute to indicate which inputs must be completed before submitting a form. This is useful for capturing important information and reducing the risk of form errors. To render a required input, apply the required attribute to the input. It is also encouraged but not mandatory to apply a required attribute to the corresponding label of the input which will automatically render a red asterisk. Note: For HTML Blueprint implementations, the required attribute is not supported on the label. Please use the alternate method specified below for rendering a red asterisk within the label.

<div class="chi-form__item">
  <chi-label for="example__required" required>Label</chi-label>
  <chi-text-input id="example__required" required></chi-text-input>

<div class="chi-form__item">
  <label class="chi-label" for="example__required">
    Label
    <abbr class="chi-label__required" aria-label="Required field">*</abbr>
  </label>
  <input type="text" class="chi-input" id="example__required" required>
</div>

Optional

When the vast majority of inputs in a form are required, optional can be used to help emphasize the few that are not. This is useful for inputs that are not relevant to all users, such as an Address Line 2 text input in a Billing or Shipping address form. If the user does not have an apartment, suite, or unit number, applying optional to chi-label will help convey the labels corresponding input is not required and can be skipped. Note: For HTML Blueprint implementations, the optional boolean attribute is not supported on the label. Please use the alternate method specified below for rendering optional text within the label.

  </label>
  <input type="text" class="chi-input" id="example__optional">

Help

Use chi-label__help to include a help icon that displays helpful information about an input in a popover. A help icon must be contained within an icon button to ensure it receives focus when a user tabs through a form.
