Anda para blogger tentu tahu apa itu daftar isi atau sitemap, daftar isi digunakan untuk memudahkan pengunjung menjelajahi blog kita karena daftar isi menampilkan semua posting atau artikel yang kita buat, Mungkin sudah banyak yang share tentang widget daftar isi. Tapi kali ini saya akan membahas cara menambahkan widget daftar isi dengan banyak pilihan dari Bloggerbelog. Widget daftar isi ini dilengkapi dengan fitur berdasarkan label dropdown dan juga bisa menampilkan ringkasan postingnya juga. tadinya menggunakan hosting java script tapi saya ambil kodenya/scriptnya agar nanti loading lebih ringan, dan juga kita bisa memodifikasinya denagn lebih leluasa. Lihat contohnya:
Untuk pemasanganya sangat mudah, anda bisa menambhakan widget ini pada sidebar ataupun halaman posting.
Berikut cara pemasanganya:1. Masuk ke Tata Letak » Tambah Gadget » HTML/JavaScript Kemudian letakkan kode berikut ini:
<div style="background:#FFFFFF; no-repeat scroll 0 0; border:2px solid #ddd; height:360px; overflow:auto; padding:10px; width:300px;">Silahkan anda sesuaikan sendiri, lihat kode yang saya beri warna.
<div id="cl_option">Loading... </div><div id="cl_content_list"></div>
<script type="text/javascript">var jumlah_kata_dalam_ringkasan = 250;</script>

Sedikit:
#FFFFFF = warna background
360px = tinggi widget
300px = lebar widget
250 = jumlah karakter pada ringkasan
Untuk area java script lihat tulisan yang berwarna merah dan biru, silahkan anda ganti sendiri, dan untuk tulisan yang berwarna biru itu merupakan simbol » & « yang jika di klik akan menampilkan dan meyembuyikan ringkasan postingnya.
Ganti http://www.MDF-BLOG.BLOGSPOT.com dengan alamat blog atau website anda. Selamat mencoba, Semoga Bermanfaat.
