Hello,

Thanks for details . I was able to see the behavior you described (hover Item Style) with UltraWebMenu on FireFox 4.0b12. UltraWebMenu is not supported on Firefox 4.0. The below link from our website will provide more details on supported environments:

<https://ko.infragistics.com/support/supported-environments>   

Expand “NetAdvantage for Web Client –ASP.NET” on Supported Environments page.  It will give you more details on product support for classic controls (like UltraWebMenu). As such, I recommend using WebDataMenu instead, since our ASP.NET AJAX controls are supported with Firefox.

I have used the following markup for UltraWebMenu to test:

<ignav:UltraWebMenu Id="UltraWebMenu1" runat="server" Height="29px" TargetFrame="eContent" Width="100%"  Font-Size="12px" FocusOnHover="False"
BackColor="Control" Font-Bold="True" ForeColor="DarkBlue" BorderStyle="Solid" BorderColor="#4863A0" BorderWidth="0px" TopItemSpacing="Compact">
<IslandStyle BackColor="White" BorderStyle="Solid" BorderWidth="1px" BorderColor="#4863A0" Font-Bold="true" ForeColor="#4863A0" Cursor="Default" >
</IslandStyle>
<HoverItemStyle Cursor="Default" ForeColor="White" BorderWidth="1px" BorderColor="#4863A0" BorderStyle="Solid" BackColor="DarkBlue">
<Margin Bottom="0px" Left="0px" Top="0px" Right="0px"></Margin>
</HoverItemStyle>
<ItemStyle Cursor="Default" >
<Padding Left="10px"></Padding>
<Margin Bottom="1px" Left="1px" Top="1px" Right="1px"></Margin>
</ItemStyle>
<ParentItemStyle>
<Padding Left="2px" Right="2px" />
</ParentItemStyle>

The below links will give you more details on WebDataMenu features and functionality:

Hope this helps.

Please reply to this ASAP ... why is the WebMenu not working ?
I should note, that I'm using this workaround fix in my aspx page:
https://ko.infragistics.com/community/forums/f/retired-products-and-controls/36753/ultrawebgrid-error-document-getboxobjectfor-is-not-a-function/215106#215106
- Also tried removing this custom workaround, but the WebMenu still doesn't work ...

I get all the top level items in my WebMenu, but they're NOT clickable and they won't expand the children when mouse-overed !?

Please reply ASAP Infragistics, this is messed up :-(

This is the complete registration of the DLL's in the web.config, as you can see they include the latest version of the binaries from you guys, v10.3.20103.2105
