PLEASE HELP - Cataloger - formatting Category Title dif. than Item Title

[glennn.php]

in trying to form a simple list view in a page where all Categories and Items are listed, i can't seem to figure out how to format the Cat Title to look more like a heading than as just another Item, i.e. the category headings and the items are listed en masse, like this:

Equipment  < Category
Ladder
Sawhorse
Flooring      < Category
Carpet
Wood

when it would make more sense for a list to appear thus:

Equipment
  Ladder
  Sawhorse
Flooring
  Carpet
  Wood

Could someone please suggest how i might format a simple list view with my Cat Titles appearing like that...?

I thank you much,
GN
