[Vuejs]-Vue 2/Vuetify 1.5 – Show/Hide text field based on checkbox selection showing duplicated fields

Solved.

I just had to pass the product inside the row Items

Updating this

<v-flex xs12 v-for="(item, index) of rowItems" :key="index">

To

<v-flex xs12 v-for="(item, index) of rowItems[product]" :key="index">
