Form with Vanilla

With the framework Vanilla as with Fomantic UI the invalid class must be applied to the parent element; use the data-custom="*" selectors. Note that framework rules require validated inputs to be wrapped in an element with class p-form-validation:

<form>
  <div class="p-form-validation">
    <label>Name</label>
    <input class="p-form-validation__input" type="text" name="name" value="">
    <p class="p-form-validation__message"></p>
  </div>
  <div class="p-form-validation" data-custom="email">
    <label>Email</label>
    <input class="p-form-validation__input" type="email" name="email" value="">
    <p class="p-form-validation__message"></p>
  </div>
  <button type="submit" class="p-button--positive">Submit</button>
  <button type="reset" class="p-button">Reset</button>
</form>

To set it up:

1. Add the data-custom="*" to parent elements and set system setting fetchit.frontend.custom.invalid.class to is-error.
2. Add the data-error="*" to elements that will display error text.
3. For FormIt compatibility add placeholders for values and errors.

Important

Markup validators complain about an empty action, so set the page URL there.

<form> 
<form action="[[~[[*id]]]]" method="post"> 
  <div class="p-form-validation"> 
  <div class="p-form-validation" data-custom="name"> 
    <label>Name</label>
    <input class="p-form-validation__input" type="text" name="name" value=""> 
    <input class="p-form-validation__input" type="text" name="name" value="[[+fi.name]]"> 
    <p class="p-form-validation__message"></p> 
    <p class="p-form-validation__message" data-error="name">[[+fi.error.name]]</p> 
  </div>
  <div class="p-form-validation"> 
  <div class="p-form-validation" data-custom="email"> 
    <label>Email</label>
    <input class="p-form-validation__input" type="email" name="email" value=""> 
    <input class="p-form-validation__input" type="email" name="email" value="[[+fi.email]]"> 
    <p class="p-form-validation__message"></p> 
    <p class="p-form-validation__message" data-error="email">[[+fi.error.email]]</p> 
  </div>
  <button type="submit" class="p-button--positive">Submit</button>
  <button type="reset" class="p-button">Reset</button>
</form>
