[Trinidad] inputText label positioning

[Richard Yee]

Does anyone know what controls the position (above or beside) of the
label for an inputText element?
I have a page with an inputText element that is inside a
<tr:panelFormLayout>. The label is appearing above the input text
field like this:

Username:
-------------------------------------
|                                   |
-------------------------------------

what I want is the label to appear beside the input

ie.
                 --------------------------------
Username: |                               |
                 --------------------------------

Thanks,

Richard
