I've to show a history/log of user actions in a pop up for that particular user along with other information. I thought of showing latest 5 actions and place a "more" button. this "more" button will increase the display space such that 10 actions can be seen and provide a scroll as well as "less" button.
I want to know is this a good/bad approach for this.
EDIT: All this should happen without effecting the pop up height.
