How can you make dynamically generated buttons in Vue.js 3 not executing the same function

Questions:

I’m creating an application where input flexibility is of paramount. My application generates contents dynamically (input, textarea, buttons). this picture shows the bottom section separated from the top with a borderline was generated dynamically

What I want to do is, when I click the grey plus button, it should generate an additional director’s name, and director’s address fields for a PARTICULAR SECTION (separated by a grey line). Unfortunately, my application keeps adding (and removing) director’s name, and director’s address fields for all sections instead of the section where the grey button (or red button is clicked) see here. Can that be achieved in Vue.js PLEASE? I.m using the ‘add_new_director_field()’ function in my Vue.js code to add the aforementioned fields. Thanks in Advance good people. See my code below:

<script>
import NavBar from './VettingReportMenu.vue';
import BreadCrumb from './BCRPreviousDirectors.vue';
import SideLinkPreviousDirectors from './SideLinkPreviousDirectors.vue';
export default {
    data() {
        return{
            header_1: "Previous Directors",
            count: 0,
            disabled: true,
            checked: false,
            isActive: true,
            inputs: [{
            director: "",
            }], 
            sec: []
        }
    }, 
    components:{
        NavBar, BreadCrumb, SideLinkPreviousDirectors
    },
    setup(){
        let myClass = "LeftLine";
        let counts = 1;
        return myClass, counts;
    },
    methods:{
        add_new_director_field(){
            this.inputs.push(this.inputs.length+1);
        },
        remove_director_field(index){
            this.inputs.splice(index, 1)
        },
        add_new_section(){
            this.count++;
            this.isActive = false;
            this.sec.push({
                director: ''
            });
        },
        remove_section(index){
            this.count--;
            if(this.count == 0)
                this.isActive = true;
            this.sec.splice(index, 1)
        },
        trythis: function() {
        alert(this.counts);
        },
        
    }
}

Answers:

You have no pointer in your add_new_director_field method in what section inputs should be added. It’s very hard to understand from your code whats happening at all. I’d recommend to start from designing a data structure at first, then go to markup. Very quick and simplified draft how can it be:

const inputsGroup = [
{
type: 'text',
value: 'Name',
}, 
{
type: 'text',
value: 'Address',
}, 
]
data() {
return {
sections: [
{
inputs: [inputsGroup]
},
]
}
}
...
addSection() {
this.sections.push({ inputs: defaultInputs })
}
removeSection(index) {
this.sections.splice(index, 1)
}
addInputs(sectionIndex) {
this.sections[sectionIndex].inputs.push(inputsGroup)
}
deleteInputs(index, sectionIndex) {
this.sections[sectionIndex].inputs.splice(index, 1)
}
<template>
<button
@click="addSection"
>
Add section
</button>
<div v-for=(section, sectionIndex) in sections>
<div v-for="(inputGroup, inputGroupIndex) in section.inputs">
<input
v-for="input in inputGroup"
:value="input.value"
:type="input.type"
>
<button
@click="deleteInputs(inputGroupIndex, sectionIndex)"
>
Delete inputs
</button>
</div>
<button
@click="addInputs(sectionIndex)"
>
Add inputs
</button>
<button
@click="deleteSection(sectionIndex)"
>
Delete section
</button>
</div>
</template>
