I have to disable the slect options based on value selected in another select.

```
<select   ng-model="myval" ng-options="lst as lst.txt  for lst in valuedata track by $index" ></select>

   <select   ng-model="myval" ng-options="lst as lst.txt  for lst in valuedata track by $index" ></select>

```

here I get same data,but my requirement is,if I select two in first dropdown I need to disable the values less than two in second dropdown and If i select two in dropdown two I need to disable the values greater than two in first dropdown.

Any help would be appreciated.
