Categories list

Hi. Sorry for my bad english. In my side bar, I can see Archives and Sujets. I have to click on Sujets to expand and see all the sujets. It’s the same thing for Archives. I have to click on a arrow to see all the archives. For the recent posts, I can see them without clicking on an arrow. What is the way tu set Archives ant Categories working the same way than recent posts ? Thanks in advance.
