Hi Karen,
Daniel answered part of your question here: http://www.onedesigns.com/support/topic/search-box-in-esplanade
He wrote: “The one in the menu is hard coded, however the one in the top is probably a widget in the header sidebar.”
So I guess you figured out how to take the one in the header out.
As the one in the navigation bar, you’ll have to edit the header.php file.
On line 32 you will see – php get_search_form(); – just delete the whole line. Save and refresh and you should be good to go.
Hope this helps,
Andre
