Yes apparently the plugin can be styled using your sites CSS.
If you plan to do some custom styling of your list using CSS, you can add a class (class=”my_page_list”).
Then reference the element in your CSS file and style away.
# my_page_list{display: inline;}
Something like that, the “display: inline;” forces it on one line no line break before or after the element.
I have not used this plugin I am however good with CSS and WordPress. I know they both allow for very good customization. You may have to go under the hood sometimes.
