I have two buttons which add or delete a combo box when clicked. What is want is to add the combo box right below the current row and so on when "add" button is clicked. Here's the plunker

One solution is to create a recursive directive. You create a data structure to hold each user and its children (other users). Every time the "add" or "delete" button is clicked you add/remove from the list of children for the clicked user.
Please see this working Plunker
Code Sample
This is the directive:
.directive('dropDown', function($compile) {
return {
restrict: 'E',
scope: {
user: '=user'
},
controller: function($scope) {
$scope.addChild = function (child) {
var index = $scope.user.children.length;
$scope.user.children.push({
"parent": $scope.user,
"children": [],
"index": index
});
}
$scope.remove = function () {
if ($scope.user.parent) {
var parent = $scope.user.parent;
var index = parent.children.indexOf($scope.user);
parent.children.splice(index, 1);
}
}
},
templateUrl: 'dropdown.tpl.html',
link: function ($scope, $element, $attrs) {
},
compile: function(tElement, tAttr) {
// Compile the directive for recursive call.
var contents = tElement.contents().remove();
var compiledContents;
return function(scope, iElement, iAttr) {
if(!compiledContents) {
compiledContents = $compile(contents);
}
compiledContents(scope, function(clone, scope) {
iElement.append(clone);
});
};
}
};
});
This is the directive's template:
<button ng-click="addChild()">add</button>
<button ng-click="remove()">Delete</button>
<select ng-model="valueSelected">
<optgroup>
<option value="LIKE">LIKE</option>
<option value="BETWEEN">BETWEEN</option>
<option value="EXISTS">EXISTS</option>
</optgroup>
</select>
<div ng-switch on="valueSelected">
<div ng-switch-when="LIKE"><input type="text" /></div>
<div ng-switch-when="BETWEEN">
<style>
.full button span {
background-color: limegreen;
border-radius: 32px;
color: black;
}
.partially button span {
background-color: orange;
border-radius: 32px;
color: black;
}
</style>
<div ng-controller="DatepickerDemoCtrl">
<div class="row">
<div class="col-md-6">
<p class="input-group">
<input type="text" class="form-control" datepicker-popup="{{format}}" ng-model="dt" is-open="opened" min-date="minDate" max-date="'2015-06-22'" datepicker-options="dateOptions" date-disabled="disabled(date, mode)" ng-required="true" close-text="Close" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open($event)"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
</p>
</div>
<div class="col-md-6">
<p class="input-group">
<input type="date" class="form-control" datepicker-popup ng-model="dt" is-open="opened" min-date="minDate" max-date="'2015-06-22'" datepicker-options="dateOptions" date-disabled="disabled(date, mode)" ng-required="true" close-text="Close" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open($event)"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
</p>
</div>
</div>
</div>
<div ng-switch-when="EXISTS">I show when EXISTS is selected</div>
<div ng-switch-default>I show by default</div>
</div>
</div>
<!-- Recursive call to the directive -->
<ul>
<li ng-repeat="child in user.children">
<drop-down user="child"></drop-down>
</li>
</ul>
