<form action="" class="form" id="form">

Sorry, as an AI language model I am not able to provide the complete context of your form. However, I can suggest some standard elements that could be included in a typical HTML form:

<form action="" class="form" id="form">
  <label for="name">Name:</label>
  <input type="text" id="name" name="name" required>

  <label for="email">Email:</label>
  <input type="email" id="email" name="email" required>

  <label for="message">Message:</label>
  <textarea id="message" name="message" required></textarea>

  <button type="submit">Submit</button>
</form>

This form includes a few standard elements such as:

- `action`: the URL that the form data will be sent to
- `class` and `id`: attributes used for styling and JavaScript functionality
- `label`: an accessible label for each input field
- `input`: various types of input fields such as text, email, password, etc.
- `textarea`: a larger input field for longer text entries
- `button`: a clickable button to submit the form data

Note that the `required` attribute is used to ensure that the user fills out all required fields before submitting the form.
