is possible to have multi dimensional array with dynamic index in html form?

I have a form with some input that each input have a plus-button and minus-button to append and remove itself, in other word we have many "resume-part", each "resume-part" have many "resume-item", each "resume-item" have many "h4", "h5", "paragraph" and "list-item" these field fill and use inside the html code dynamic with php.

this is the form html code :

        <form class="card" action="" enctype="multipart/form-data" method="post">
      @csrf
      <div class="card-header">
        <h3 class="card-title">Resume</h3>
      </div>
      <div class="card-body">
        <div>
          <div class="mb-3">

            <input type="text" class="form-control" name="programming_portfolio_resume_title" value=""/>
          </div holder>
            @for($i = 0 ; $i < count(@get_field('programming_portfolio_resume_part') ?? array_fill(0, 1, null)) ; $i++)
              <div resume-part class="mb-3">
                <div class="card">
                  <div class="card-header">

the question is how to set dynamic index for html form ? I mean after send and save the form, I want to get for example programming_portfolio_resume_part[0]['item'][1]['paragraph'][3]

and the first dimension index (in here the index of programming_portfolio_resume_part[]) be the same in each form loop.

but now the first index increased by each time I use programming_portfolio_resume_part in the name of form element.
