see if iview is possible. I remember there is a multi-level linkage

the train of thought is not difficult

remember a nested object. Your description should be 3 layers 

[
    {
        name: '1',
        checked: true,
        children: [
            {
                name: '1-1',
                checked: true,
                children: {
                    name: '1-1-1',
                    checked: true
                }
            }
        ]
    }
]

what you need to do is to click on the children, below this level and set the checked in the children to the green of true. Each check / uncheck simply change the checked of the current child and update the number of selected parent components

as for animation, it is simple and practical to use css3 transition. Change the hidden display to a change in left or a change in width

has the landlord solved it? can you send a copy using iview
