こんな感じです。
このオブジェクトを操作するようなウィジットになってます。

</b:includable>
</b:widget>気をつけておかないといけないことが数点あります。
- <h2>がらのうつうつ日記 TabView Widget</h2>はお好きなタイトルを
- labels1 には集約して表示したいラベルを
- nPostには一度に表示したい件数を
]]></b:skin>の手前に定義しています。
/*tabview
----------------------------------------------- */
.tabview li {
text-align: left;
}とりあえず、今はこれしか入れてないですけど。。。
これでもう少し勝手が効くかな？
こういうことができるってことは、他のYahooUIを使って楽しいことができそうでもあるなぁ～
