QUESTION
I'm using v-intersect

If you want to use CSS then you can assign a closed
and open
classes (name them whatever) and change for each class name you have your set of css properties (width) etc. you can use transition
css property to animate it.
Then to get it to go from one to the other you'll still need to add or remove the class from the element using JS which is easy to do.
- Use JS to select the element
- Use
classList
to add/remove classes as needed
