For unknown reason the ± open close icons of my tree are not displaied(drawn). It appear only a small white box. Is there anything I need explicitly do?
Hi, most probably there’s something wrong with the CSS. First of all, please check whether the webix.css is connected properly to your project.
Also, something in your custom style may override .webix_tree_(open/close).
Solved, thanks. I did not create the /fonts subfolder.
