Modifying DOM (slideDown/slideUp) with AngularJS and jQuery

Question

I\'m trying to implement a slideDown/slideUp animation with AngularJS. I can\'t use CSS3\'s transition (unfortunately) since the height is set to auto

Answer 1

I want to show an example of how this is done with ng-if, since I was looking for a solution for hours running into multiple completely different approaches that work with ng-show only. You may use ng-if vs ng-show if say you need directives initialized only upon becoming visible.

To use jQuery slideDown / slideUp with ng-if, you can also use ngAnimate but using different hooks: enter and leave.

app.animation('.ng-slide-down', function() {
  return {
    enter: function(element, done) {
      element.hide().slideDown()
      return function(cancelled) {};
    },
    leave: function(element, done) { 
      element.slideUp();
    },
  };
});


     I will slide down upon entering the DOM.

This was surprisingly difficult to accomplish, even trying various JS based approaches and CSS only approaches. Ultimately there is a time and place for jQuery's animations.
