Responsive comments section using Vue Framework with Vuex

I would love to get feedback on Vue code arrangments as this is the first time I'm using the Vue-Cli.

Also, I faced a problem transitioning the comment cards in replies using Vue's inbuilt <Transition> tag, the main comments list works fine but the animation doesn't work when wrapping the replies section with <Transition>, any ideas on how to do such thing? or if there is any other way I could animate this?

thanks in advance. <3
