Custom menus

Use the Custom Menu widget in Appearance -> Widgets?

Ok nevermind.. I also want to change that orange color background behind the slider..
what should i do?

and sorry for using uppercase last time ??

What theme are you using? Where did you download it from?

Orange background on your site is part of image that is much bigger and its called body.png. The image is +1000px high and 1px width. In order to change that you will need to edit in photoshop and name it body.png and replace it with existing body.png picture. If you need more help let me know.

The custom menu can be added manual.

I’m sorry but as you are using a non-WPORG theme, you need to seek support from the theme’s developers – paid or otherwise. We only support themes downloaded from www.remarpro.com here.

In the meantime, try using Firefox with the Firebug add-on for this kind of CSS troubleshooting. Or use whatever developer tool is available in your web browser.

Yup you need to recreate the background image and change the background color of the animation through css.
