Angular CDK Overlay Tutorial: Adding Animations

When using the Angular CDK Overlay module, you will likely want to transition the opening and closing of the overlay content. It’s something that seems like it should be pretty easy and straightforward but it’s actually a little tricky. It can’t really be transitioned with CSS only because it’s markup that gets added into and removed from the document. It’s not a simple style or class change. We need to leverage Angular animations to make it work well. In this post I’ll show you why and I’ll show you how to make animations work for your overlays. Alright, let’s get to it!

Angular CDK Overlay Tutorial: Scroll Strategies

In the Angular CDK there are a lot of cool, exciting, and helpful features. And the Overlay Module is one of the most powerful. It’s used to create things like dialogs, tooltips, menus, custom dropdowns and more. I’ve already created a couple of posts on the Overlay Module, one where I cover the basics of setting them up, and another where I demonstrate different ways that they can be positioned within the viewport. If you’re unfamiliar with these concepts and haven’t read those, you should do that before rreading this one because we will build off the examples that we created in them. Here, we’ll be focused on how we want an overlay to react when scrolling the container it’s positioned within.

I’d suggest that if you’re unfamiliar with the Overlay module at all, you go check out that post first because the demos in this video will build off the examples we built, and concepts that we learned. In this post we are going to learn about different ways to control how a pop-up gets positioned when using a connected overlay because there’s a lot to it and it’s all pretty cool.

Angular CDK Overlay Tutorial: Learn the Basics

When building apps in Angular, you will likely need to trigger a modal or pop-up at some point. Sometimes this is easy and can be done with some simple CSS, but other times, it may be more complicated. You may need to append markup to the bottom of your document so that it can be placed on top of everything else. Or maybe depending on scroll position, a pop-up will need to open upward instead of downward. There’s lot’s of possible scenarios where you may need more than what’s capable with CSS by itself and that’s where the CDK Overlay Module comes into play.

How to Use Angular @Input to Pass Data to Dynamically Created Components

If you’re using dynamically created components in Angular, you’ve probably found it difficult to pass information between the parent and child components when needed.
