Drop down text options

I'm looking for feedback on other options for displaying drop down text. I'm getting feedback from my users that they don't understand that green italic text (or what ever format is used) assumes drop down text. Most people are now used to seeing collapse and expand icons to represent drop down information. I have used the twisties in some of my projects but in this specific case, i am using the Show/Hide All script and there appears to be a conflict with the 2 scripts.

I'm just curious if there are other methods used to represent or display that an item on the page is a drop down link, other than expand or collapse icons.
