Field
Defines a form field
The Field
component sets the provided field name into the context so child
components like input fields and labels can retrieve it and use it as
the default field.
<Form for={:user}>
<Field name={:email}>
<Label>E-mail</Label>
<div class="control">
<TextInput value={@user["email"]}/>
</div>
</Field>
</Form>
