Good evening! Please help me figure out how to add new fields on click. There are no problems with the list. There you draw from the array to data via v-for onto the page. But what about input? It should work like this:
Click on the button -> A new input c label is added.

PS tried to do so, but the field appears only at the time of loading. After, it disappears...
