Here you go : http://plnkr.co/edit/8YV6cdCIPCjEOq3DtjAz?p=preview
First : added the following to the directive :
scope:{
menuItems:"=menuDemo"
},
This enable the two-way binding on the data you pass to the menu-demo attribute when using your directives, without this you can't pass data to your directive.
Second : remove the script tag in the tree-renderer.html and sub-tree-renderer.html. Script tag is only usefull when using ng-include along with it. You were just define a template part without using it like this.
Third adding a top level ng-repeat for the 1st level in tree-renderer.html and remove the one from index.html.
<div ng-repeat="menuItem in menuItems">
As you can see menuItems match with what i have defined in the scope:{} part.
Fourth : I added the binding of the function addItem and addSubItem so you can define your own way of adding items to the tree outisde of the directive.
EDIT : Another plnkr where i move out the <div ng-repeat="menuItem in menuItems"> http://plnkr.co/edit/MZ3nsY6WTG3EiNKhXjAv?p=preview.
As you can see i put the menu-demo call in a <span> tag within the <li> tag. This is because they both use isoled scope and if i want to use data from the ng-repeat loop the easiest way is to move the other directive in a child DOM element.
Note that i also change the name of the binding element to menuItem (i remove the 's').

Sorry, but first div tag in 'tree-renderer.html' is unnecessary for me. How can I transfer 'ng-repeat' from that div ?

This doens't work: <li ng-repeat="menuItem in menuItems" class="menu" menu-demo="menuItems" menu-add-item="addItem" menu-add-sub-item="addSubItem"></li>

It's better but do you have any other ideas? That span breaks css :(

i would need the said css for this or that you point me what is not working, i don't have anything that seems to break in my fiddle.

i just retested without the span and it work now... strange here is the line :
<li ng-repeat="menuItem in menuItems" class="menu" menu-demo="menuItem" menu-add-item="addItem" menu-add-sub-item="addSubItem"></li> |
That is not a correct way to declare a directive try something like this:
angular.module('myModule')
.directive('menu', [function () {
return {
restrict: 'A',
scope: true,
templateUrl: 'tree-renderer.html',
link: function ($scope, $element, $attrs) {
//here some functions that do something
}
};
}]);
By the way, try improve your questions!
