How long do you think it might take?

Question

Vue.js

I am too green to give an estimate of the time for this project, so I ask the more "high" magicians in our area to give at least a rough estimate.
On 1) There are blocks, the same rectangles that can be dragged to the field number 2, as you can see, you can change the name and add new blocks.
Also, I beg you to help with the choice of a library (for vue.js) to make the creation of this creation as easy as possible
. Thanks for the advice!
