I am currently utilizing the navigation menu in the ASP.NET toolbox, but I am struggling to remove an unwanted golden border. Despite my efforts, I have not been able to find any information on how to resolve this issue. The golden border only appears when I click on a navigation item, and it disappears when I click somewhere else on the page (since the navigation menu operates with JavaScript and does not redirect to another page). After inspecting it with Firebug, I noticed that a CSS class called "highlighted" is added to the item when it is clicked on. Can someone please advise me on how to eliminate this golden border?
