in coupon theme, in header search all coupon categrories not coming?

visit my website couponmoz.com. if you see in header search there are three option All coupons, all stores and search.
in all categories only 4 categories coming because of in child theme ‘function code.php’ is static
this is the code
<form action=”<?php echo get_home_url(); ?>/” method=”get” class=”nsearch hidden-sm hidden-xs”>

<div class=”row clearfix”>
<div class=”col-md-4″>
<select class=”form-control f1″ name=”stype”>
<option value=”” <?php if(isset($_GET[‘stype’])){ selected( $_GET[‘stype’], “” );} ?>><?php echo $CORE->_e(array(‘coupons’,’48’)); ?></option>
<option value=”1″ <?php if(isset($_GET[‘stype’])){ selected( $_GET[‘stype’], 1 );} ?>><?php echo $CORE->_e(array(‘coupons’,’9′)); ?></option>
<option value=”2″ <?php if(isset($_GET[‘stype’])){ selected( $_GET[‘stype’], 2 );} ?>><?php echo $CORE->_e(array(‘coupons’,’10’)); ?></option>
<option value=”3″ <?php if(isset($_GET[‘stype’])){ selected( $_GET[‘stype’], 3 );} ?>><?php echo $CORE->_e(array(‘coupons’,’11’)); ?></option>
</select>
</div>
