Angularjs: ng-options with group -


i have 1 level tree situation:

<select ng-model="tipost"          ng-options="tip.desc group tip.tipis tip in tipall"><br> </select>



json is: 

    [      {"id":"1", "idparent":"0", "tipis":"", "desc":"groupname1"},      {"id":"2", "idparent":"1", "tipis":"groupname1", "desc":"childname1"},      {"id":"3", "idparent":"0", "tipis":"", "desc":"groupname2"}     ]



problem creates optgroups children repeats roots too:

- groupname1 - groupname2 [ groupname1 ] - childname1 [ groupname2 ]


want produce:

[ groupname1 ] - childname1 [ groupname2 ]


thanks in advance.

the grouping doesn't quite work that, if change json this:

[  {"id":"1", "tipis":"groupname1", "desc":"name"},  {"id":"2", "tipis":"groupname1", "desc":"name1"},  {"id":"3", "tipis":"groupname2", "desc":"name2"},  {"id":"4", "tipis":"groupname1", "desc":"name3"}, ]

then you'll grouping way want
