Removing Previous Button on First Step jQuery Steps

Question

I'm using jQuery Steps for my site signup wizard, works awesome with the exception that on the first step I'm getting the previous button, which really makes no sense since there is no previous content.

I looked at the onInit() function in the API but there is no setting for enablePreviousButton, only enableFinishButton and enableCancelButton.

Is there a way I can remove the Previous button on the first step?

Requested code:

$("#register-form").steps({
    headerTag: "h3",
    bodyTag: "fieldset",
    autoFocus: true,
    onInit: function (event, current) {
        alert(current);
    },
    labels: {
        finish: 'Sign Up <i class="fa fa-chevron-right"></i>',
        next: 'Next <i class="fa fa-chevron-right"></i>',
        previous: '<i class="fa fa-chevron-left"></i> Previous'
    }
});

HTML:

<h3><?= $lang_wizard_account; ?></h3>
<fieldset>
    <legend><?= $lang_text_your_details; ?></legend>
    <div class="form-group">
        <label class="control-label col-sm-3" for="username"><b class="required">*</b> <?= $lang_entry_username; ?></label>
        <div class="col-sm-8">
            <input type="text" name="username" value="<?= $username; ?>" class="form-control" placeholder="<?= $lang_entry_username; ?>" autofocus id="username" required>
            <?php if ($error_username) { ?>
            <span class="help-block error"><?= $error_username; ?></span>
            <?php } ?>
        </div>
    </div>
    <div class="form-group">
        <label class="control-label col-sm-3" for="firstname"><b class="required">*</b> <?= $lang_entry_firstname; ?></label>
        <div class="col-sm-8">
            <input type="text" name="firstname" value="<?= $firstname; ?>" class="form-control" placeholder="<?= $lang_entry_firstname; ?>" id="firstname" required>
            <?php if ($error_firstname) { ?>
            <span class="help-block error"><?= $error_firstname; ?></span>
            <?php } ?>
        </div>
    </div>
    .... 
</fieldset>

Answer 1

This has the same effect, but is way less hack-y:

.wizard > .actions > ul > li.disabled {
  display: none;
}

Answer 2

Ok, pretty ugly hack but it does work as expected:

$("#register-form").steps({
    headerTag: "h3",
    bodyTag: "fieldset",
    autoFocus: true,
    onInit: function (event, current) {
        $('.actions > ul > li:first-child').attr('style', 'display:none');
    },
    onStepChanged: function (event, current, next) {
        if (current > 0) {
            $('.actions > ul > li:first-child').attr('style', '');
        } else {
            $('.actions > ul > li:first-child').attr('style', 'display:none');
        }
    },
    labels: {
        finish: 'Sign Up <i class="fa fa-chevron-right"></i>',
        next: 'Next <i class="fa fa-chevron-right"></i>',
        previous: '<i class="fa fa-chevron-left"></i> Previous'
    }
});

This is a good solution using jQuery:

$("a[href$='next']").hide();
$("a[href$='previous']").hide();

This solution allow you to call .click() function to go next or previous, like this:

$("a[href$='next']").click();

or

$("a[href$='previous']").click();
