title: javafx treeview css how to add line after every parent node
body: <p>In JavaFx treeView, how to add line after every parent node ? Please refer to my code below. I tried to select only child node in css and apply border with top transparent and select only parent node and apply border with bottom transparent. </p>
  
  <pre><code>.tree-view .tree-cell {
     -fx-indent: 0;
   }
   .tree-cell:filled:selected {
     -fx-border-color: transparent #111111 #111111 #111111;
     -fx-background-color: rgb(100,100,100,0.2);
    }
   .tree-cell:hover .highlight-on-hover { /* not working, this is where I need some help */
     -fx-border-color: transparent #111111 #111111 #111111;
     -fx-background-color: rgb(100,100,100,0.2);
    }     
  </code></pre>
  
  <p>This is causing a line in between my parent and child node which I want to eliminate. How to do that ?</p>
