How to edit wp_list_categories

or is this even possible?

View your source of your page. Find
li id=”categories-1″ class=”widget widget_categories”
This is categories widget class. For ul, you can use,
.widget_categories ul{
}

Thanks, yakuphan.

That is my plan B if i can’t figure out a way to add a class name to the UL in mind.

Actually you have to enclose the function in your own list. See the examples here.

You need to add the opening and closing tags for the list, so you can give that list whatever class or ID you like…

The function only creates the list elements, and not the actual containing list.

but i have the categories as an item in my widgetized sidebar.

when i view my page in a browser and look at the source code, i see the wp_list_categories LIs all wrapped in a UL and /UL tags. but where in the php files is that opening UL tag? i can’t find it anywhere.

Open wp-includes/default-widgets.php and see line 460 for WordPress 2.8.4
Edit this UL.
