This works for me:
.mce-path {/* CSS */
display: none !important;
}
EDIT:
In TinyMCE4, I don't think there is an official way to do it by passing a parameter to tinymce.init();
to disable the path. You can pass statusbar: false
but that will hide the path AND the resize icon, unfortunately!
The answer I gave by using CSS, hides the path but the resize icon stays there. But make sure you have the statusbar: true
in the tinymce.init();
