實在不好意思...
最近都很忙....很晚才post 這個教學....

Steps
============================================
1.  側邊欄位設定 -> 新增版位 -> (隨便給個名字)
2. 將剛才新增的版位拖拉至右行 (本教學假設該版面分佈像 pigirl.pixnet.net
3. "設定"剛才新增的版位
4. Copy 下面的 javascript code, and paste on 剛才新增的版位
5. 送出
6. 儲存版面
7. 完成!

微調　（更改位置）
－－－－－－－－－－－－－－－－－－－
floatingMenu.targetX= -180;　　＜－－　預設 X 軸位置
floatingMenu.targetY=-110;　　　＜－－　預設 Ｙ 軸位置


Javascript Code
