Updating Navbar Components: Adding Chevron Animation in Dropdowns

I was wondering how you all update components! I have some older components I use (Navbar 2 and its dropdowns) and there are "newer" ones on the relume site that have a cool chevron that flips around on hover (animation?) versus the previous which just had an icon that was static.. I want to update to the new chevron with animation - I am trying to cut and paste in the chevron.. (managed to do that) but the animation doesnt come with it because I believe it attached to the parent element.. I started trying to copy that.. but its very hard to understand for me if the animation from one dropdown (ie navbar-dropdown1) can work with my component navbar2-dropdown 😄
