dede的欄目只能循環(huán)一次。所以需要修改
織夢網(wǎng)站建設(shè)跟板網(wǎng)在5.7中試驗(yàn)了一下可以用。　　修改文件：\include\taglib目錄下的channel.lib.php，請將以下代碼全部復(fù)制替換上述文件。

模板調(diào)用 [field:sonchannel0][/field:sonchannel0]這個(gè)是用來取子欄目用得（使用[sonchannel+數(shù)字]作為標(biāo)簽名是為了防止嵌套的時(shí)候無法正確解析標(biāo)簽）
這個(gè)的作用就是當(dāng)你的欄目有很多子欄目無限分級的時(shí)候方便你取子欄目的
