Yes, the search box control is implemented with a single token, but using the header.xml file you can adjust the separate parts.

You can refer to the User's Guide, in particular the Token reference at the end.

thanks steve,

can you tell me where this guide is please?

I've looked everywhere i can think of including:
Support >> Documentation >> Downloadable files
Development >> Downloads
Help
Forge

I can't think where else it would be ..?
(I always seem to struggle finding content on DNN site - wouldn't mind being involved in website user feedback if ever there was a user survey)

anyway, I managed to solve the issue.
I thought I was doing something wrong - as the header.xml file you mention - does not have a [SEARCH] or [SEARCHBOX] token in any of my template folders.

I have a [SEARCH] token in header.html, but no [SEARCHBOX] in either header file.

I copied the entire <Object> code supplied above into header.xml and it worked,

thanks,
mark.
