Hi, Monica
From just a regular user like you I would think you could do this like..
Open Control panel and find
Edit Categories
Choose the category you like to enable this on
Click
edit
Browse down to,
Additional Fields
Find the
Add a new field type:
Write a name for this as you would like it to apeare on your site. (Would you like Critique?)
Choose
Dropdown
and write in your options like shown
Add a new field type:
Yes||No||only if it's good
You might have to do this by hand to all categories.
From the control panel...
If you would like to add a new additional field, enter the text which will be used to present the options, select the type of input you want to use and then enter the default text or a list of options. Options are entered using a double-pipe || as a field seperator; to enter three options, you would enter: field1||field2||field3 as your Options field.
Then this might not be what you where looking for?
Good luck
