Help with custom tags

Hello all.

I have created a custom library set named "dbdbs: " I have applied tags to it
"helloWorld". I have set these tags to be used in JSP pages. It highlights
the code in the coding view, but it does not show any code in the GUI view.

This is a problem as my designers use the GUI view to layout the pages.
Normally it would like it to appear the same way as the jsp tags

<dbdbs:helloworld / >

Is there a way to highlight and show this code in the GUI view?

Any help would be appreciated.

Thank You in Advance
