In this example, a specific CSS rule is applied to the playlist to set its max-height, like this:
.wvpl-playlist ul {
max-height: 160px!important;
}Because of that setting, the playlist only shows the first few tracks. The hidden items can be revealed scrolling with the mouse. In addition to that, WavePlayer automatically scrolls the playlist to make the playing track always visible. The automatic scrolling occurs either when the user advances the tracks with the skip buttons and when the player jumps to the next track at the end of the current one.
