If set to true, forces the input to remain empty.

When passed to a select list, this creates a blank option with an empty value in your drop down list. If you want to have a empty value with text displayed instead of just a blank option, pass in a string to empty.

<?php echo $form->input('field', array('options' => array(1,2,3,4,5), 'empty' => '(choose one)')); ?>

1. <?php echo $form->input('field', array('options' => array(1,2,3,4,5), 'empty' => '(choose one)')); ?>

Output:

<div class="input">
    <label for="UserField">Field</label>
    <select name="data[User][field]" id="UserField">
        <option value="">(choose one)</option>
        <option value="0">1</option>
        <option value="1">2</option>
        <option value="2">3</option>
        <option value="3">4</option>
        <option value="4">5</option>
    </select>
</div>

If you need to set the default value in a password field to blank, use 'value' => '' instead.

Options can also supplied as key-value pairs.
