• Simpan Template sobat
• Teks yang saya beri warna merah, seandainya pada Template sobat  sudah berisi walaupun serialnya berbeda - bisa dihilangkan, cukup pasang satu saja
• Teks yang saya beri warna Kuning adalah jumlah Posting yang dipakai Slider, bisa dirubah

Langkah terakhir adalah memanggil Slide, disini ada dua cara 

» Langsung di Template dan » Tambah Gadget [INGAT Pilih salah satu lho]

» Langsung di Template :  

• Beri tanda check disamping  Expand Template Widget 
• Cari  <div id='main-wrapper'> 
• Copas script berikut diatasnya [sebelumnya di Parse dulu]

» Tambah Gadget :

• Pada Tata Letak pilih Tambah Gadget - HTML / JavaScript
• Copas script berikut kedalamnya

<div id='bbccarousel'>
<div id='previous_button'/>
<div class='container'>
<script>
document.write(" <script src=\"/feeds/posts/default?max-results="+numposts1+"&orderby=published&alt=json-in-script&callback=showrecentposts\"><\/script>");
</script>      
<div class='clear'/></div>
<div id='next_button'/></div>
<script type='text/javascript'>
(function($) {     $(document).ready(function(){
$("#bbccarousel .container").bbcCarousel({
    auto:4000,
    scroll: 3,
    speed: 800,  
    visible: 4,
    start: 1,
    circular: true,
    btnPrev: "#previous_button",
    btnNext: "#next_button",
    });
    })})(jQuery)  
</script></div></div></div>

• Simpan Kembali Template / Blog sobat

Kelebihan Slider Carousel untuk Daftar Isi ini selain bisa dipanggil lewat Gadget juga bisa dipakai untuk Slider berdasarkan Label / Katagori 

Caranya sebagai berikut :

misalnya sobat ingin Slide dengan Label tutorial maka 

• numposts1 =50, bisa sobat sesuaikan dengan jumlah Label yang ingin dipakai Slide 
• Tambahkan  label1="tutorial", dibawah  numposts1 = 50; 
• Ganti  <script src=\"/feeds/posts/default?max-results="+numposts1+"&orderby=published&alt=json-in-script&callback=showrecentposts\">  dengan  <script src=\"/feeds/posts/default/-/"+label1+"?max-results="+numposts1+"&orderby=published&alt=json-in-script&callback=showrecentposts\">
• Simpan Template sobat
