How to get rid of ugly asp:Menu flickering?

Question

I\'m using the asp:Menu control on an ASP.NET 4.0 Webforms page with table-free rendering mode:

Answer 1

If anyone still needs a solution; the flickering is there because you should set the correct display style in your css for the menu.

Try for example

#menu ul li ul
{
    display: none;
}

and

#menu ul li 
{
    position: relative; 
    float: left;
    list-style: none;
}

The flickering is because the ASP.NET 4 menu uses javascript to set some inline styles.
