I\'ve seen an example somewhere online showing how to customise the appearance of jstree\'s right-click context menu (using contextmenu plugin).
For example, allow
To clear everything.
Instead of this:
$("#xxx").jstree({ 'plugins' : 'contextmenu', 'contextmenu' : { 'items' : { ... bla bla bla ...} } });
Use this:
$("#xxx").jstree({ 'plugins' : 'contextmenu', 'contextmenu' : { 'items' : customMenu } });
