I'm trying to create a navigation bar using AngularJS. I need to show and hide the submenu 'div.farm-links' on mouseover and mouseleave respectively on 'div.menu-links'.
I'm supposed to delay the mouseover on 'menu-links' by 0.5 sec, and similarily on mouseleave, the effect should happen after 0.5 sec. But somehow, this doesn't seem to work.
Could you please help me correct this? Also, is that possible to achieve using CSS only?

</nav>You have to define hovering on $scope. You can use an array to show the corresponding rows on ng-repeat
JS:
$scope.hovering=[];
$scope.showDiv = function(index) {
$timeout(function() {
$scope.hovering[index] = true;
}, 500);
};
$scope.hideDiv = function(index) {
$timeout(function() {
$scope.hovering[index] = false;
}, 500);
};
HTML:
<div ng-repeat="obj in pageData.allChildList" class="hiding-div" ng-mouseover="showDiv($index)" ng-mouseleave="hideDiv($index)" >
<div>
