用mui框架吧，weui没有这种控件。

测试了一下，可以的，参考代码

        Dim wb As New WeUI
        Dim txt As String = "由各种物质组成的巨型球状天体,叫做星球.星球有一定的形状,有自己的运行轨道."
        '增加三个页面,一个按钮
        With wb.AddTabBar("", "tb1", 1)
            .AddPage("page1","微信","./images/button.png")
            .AddPage("page2","通讯录","./images/msg.png")
            .AddPage("page3","发现","./images/article.png")
            .AddButton("bt1","我","./images/cell.png","http://www.foxtable.com")
        End With
        '为第一个页面增加内容
        wb.AddForm("page1","form1","test.htm")
        With wb.AddInputGroup("form1","ipg1")
            .AddInput("xm","户名","text")
            .AddInput("mm","密码","password")
        End With
        With wb.AddButtonGroup("form1","btg1",True)
            .Add("btn1", "确定", "submit")
        End With
        '为第二个页面增加内容
        With wb.AddPanelGroup("page2","pg1","图文组合列表")
            .Add("pn1","标题一",txt,"./images/button.png","http://www.foxtable.com")
            With .Add("pn2","标题二",txt,"./images/search.png")
                .AddFoot("文字来源")
                .AddFoot("时间")
                .AddFoot("|其他信息","http://www.foxtable.com")
            End With
            .GroupFoot = "查看更多"
            .GroupHref = "http://www.foxtable.com/"
        End With
        '为第三个页面增加内容
        With wb.AddArticle("page3","ar1")
            .AddTitle("h1","发现")
            .AddTitle("h2","章标题")
            .AddTitle("h3","1.1节标题")
            .AddContent(txt)
            .AddImage("./images/001.jpg")
            .AddTitle("h3","1.2节标题")
            .AddContent(txt)
            .AddImage("./images/002.jpg")
        End With
        wb.InsertHTML("<style>.weui_navbar {top:auto; bottom: 0;}</style>")
        wb.InsertHTML("<style>.weui_navbar + .weui_tab_bd {padding-top: 10px;}</style>")
        e.WriteString(wb.Build)
