How do I make a component like this in Eclipse Java WindowBuilder? -

i make such tree-like component many roots. component should use? jtree doesnt allow multiple parents.

you can achieve using normal jtree , set setrootvisible property false

 jtree.setrootvisible(false); 

example

   jframe frame = new jframe();     ///adding mock data     defaultmutabletreenode root = new defaultmutabletreenode("root");     (int = 1; < 5; i++) {         defaultmutabletreenode parent = new defaultmutabletreenode("parent" + i);         (int j = 1; j < 5; j++) {             parent.add(new defaultmutabletreenode("child" + j));         }         root.add(parent);     }      defaulttreemodel model = new defaulttreemodel(root);     jtree tree = new jtree(model);      tree.setrootvisible(false);//to hide root      frame.add(new jscrollpane(tree));     frame.settitle("tree roothide example");     frame.setdefaultcloseoperation(jframe.exit_on_close);     frame.pack();     frame.setvisible(true); 

example output
