Rendering multiple nested fieldset in laminas form

Hi everyone.
I’m coming back with my fieldset in laminas-form.
I have 5 nested fieldsets like this :
Impact → Effet → Composante → Produit → Activite
I use a loop function to render each element of a fieldset and it works.
I would like to use the Javascript function to add more elements for each fieldset but the data-template does not render my elements as I would like to have.

Here is how I render my elements and this is how I want to render it :

<div class="row clearfix">
	<div class="mb-0 col-lg-4 col-md-4 col-sm-4 form-control-label">                                    
		<label class="" for="ImpactForm[effets][0][composantes][0][produits][0][activites][0][libelle]">Intitulé de l'activité</label>
	</div>
	<div class="mb-0 col-lg-8 col-md-8 col-sm-8">
		<div class="form-group ">
			<input type="text" name="ImpactForm[effets][0][composantes][0][produits][0][activites][0][libelle]" class="form-control champ-requis" value="">            
		</div>
	</div>
	<div class="col-lg-12">
		<div class="form-group error-message mt-0"></div>
	</div>
</div>

How can I render elements in each fieldset like the code above ?

I post all my code below :

  1. The main form

<?php

use Commun\Form\Modules\Application\Fieldset\ImpactFieldset;


use Commun\Form\CommunForm;

{
            
    public function init() {        
        $this->setName('CadreLogiqueForm');
        $this->addFieldset(ImpactFieldset::class,['use_as_base_fieldset' => true]);
        $this->addSubmitButton('next', 'Poursuivre', 'next', 'btn btn-vert w-100');        
        $this->addSubmitButton('previous', 'Précédent', 'previous', 'btn btn-rouge w-100');

Here is my code for generating form elements. The question is how to generate the data-template with my first html code ?
Any help would be very appreciated because I stuck on this for weeks.

Thanks !

Hello,
I have found the solution to my problem !

Can you share your solution for the current problem? Thanks in advance! :+1:t3:

Here is my solution :
I Change my partial view for rendering elements from nested fieldset like this :

<?php 
foreach ($form as $element){    
    $classCheckBox='';
    if(!($element instanceof Laminas\Form\Element\Collection) && ($element->getAttributes()['type']=='multi_checkbox')){
        $classCheckBox = 'icheck-default';
    }    
    
?>
<!--We render elements wich are not collections-->
<?php if(!($element instanceof Laminas\Form\Element\Collection)): ?> 
    <?php if(!($element instanceof Laminas\Form\Element\Button)): ?>
    <div class="row clearfix">
        <?php if($setLabel): ?>
        <div class="mb-0 col-lg-<?=$colLabel?> col-md-<?=$colLabel?> col-sm-4 form-control-label">                                    
            <?= $this->formLabel($element) ?>
        </div>
        <?php endif; ?>
        <div class="mb-0 col-lg-<?=$colInput?> col-md-<?=$colInput?> col-sm-8">
            <div class="form-group <?=$classCheckBox?>">
                <?= $this->formElement($element) ?>            
            </div>
        </div>
        <div class="col-lg-12">
            <div class="form-group error-message mt-0">
                <?= $this->formElementErrors()->render($element) ?>
            </div>
        </div>
    </div>
    <?php else:?>
        <div class="text-right col-lg-12 mt-15">                                    
            <?= $this->formButton($element); ?>   
        </div>
    <?php endif;?>
<?php else : ?>
<?php 
  $effetFieldsets = $element->getFieldsets();  
  $effetsFieldset = $form->get('effets');
  
?>
    <div class="nested-fieldset">
        <?php 
            $this->formCollection()->setWrapper('<div class="nested-fieldset">%2$s%1$s%3$s</div>');
            $this->formCollection()->setElementHelper($this->formRow()->setPartial('partial/cadre-logique/view-rendering-cadre-logique-collection-elements-2'));
            echo $this->formCollection($effetsFieldset);            
        ?>
    </div>
<?php endif; ?>
<?php    
  }
?>

this line : $this->formCollection()->setWrapper('<div class="nested-fieldset">%2$s%1$s%3$s</div>'); is for surrounding each nested fieldset in a div with a class called ‘nested-fieldset’
And the view-rendering-cadre-logique-collection-elements-2 look like this :

<div class="row clearfix">
    <?php if(!($element instanceof Laminas\Form\Element\Button)): ?>
        <div class="mb-0 col-lg-4 col-md-4 col-sm-4 form-control-label">                                    
            <?= $this->formLabel($element) ?>
        </div>
        <div class="mb-0 col-lg-8 col-md-8 col-sm-8">
            <div class="form-group">
                <?= $this->formElement($element) ?>            
            </div>
        </div>
        <div class="col-lg-12">
            <div class="form-group error-message mt-0">
                <?= $this->formElementErrors()->render($element) ?>
            </div>
        </div>
    <?php else : ?>
        <div class="text-right col-lg-12 mt-15">                                    
            <?= $this->formButton($element); ?>   
        </div>
    <?php endif; ?>
</div>

And then here is my JS File for adding more elements for each fieldset :

$( document ).ready(function() {    
     ajouterActivite();
     ajouterProduit();
     ajouterComposante();
     ajouterEffet();
});

function ajouterActivite(){    
    $('body').on('click','.btnAddActivite',function (){          
        var parentNested = $(this).parent().parent().parent().find('.nested-fieldset');            
        var currentCount = $(parentNested).length - 1;                  
        var template = $(parentNested).find("span").attr("data-template");        
        template = template.replace(/__activite__/g, currentCount);
        $(this).parent().parent().before(template);
        
        return false;
    });
    appliquerMasqueMontant(); 
}

function ajouterProduit(){              
    $('body').on('click','.btnAddProduit',function () {
        var parentNested = $(this).closest('.nested-fieldset').find('.nested-fieldset');               
        var currentCount = $(parentNested).length;        
        currentCount = (currentCount -1)/3;        
        var template = $(parentNested).next("span").attr("data-template");        
        template = template.replace(/__produit__/g, currentCount);
        $(this).parent().parent().before(template);

        return false;
    });
    appliquerMasqueMontant(); 
}
function ajouterComposante(){
    $('body').on('click','.btnAddComposante',function () {
        var parentNested = $(this).closest('.nested-fieldset').find('.nested-fieldset');               
        var currentCount = $(parentNested).length;        
        currentCount = (currentCount -1)/5;        
        var template = $(parentNested).next("span").attr("data-template");        
        template = template.replace(/__composante__/g, currentCount);
        $(this).parent().parent().before(template);

        return false;
    });
    appliquerMasqueMontant(); 
}
function ajouterEffet(){
    $('body').on('click','.btnAddEffet',function () {
        var parentNested = $(this).parent().parent().find('.nested-fieldset');          
        var currentCount = $(parentNested).length;
        currentCount = (currentCount -2)/7;       
        var template = $(parentNested).find('.nested-fieldset').next("span").attr("data-template");                
        template = template.replace(/__effet__/g, currentCount);
        $(this).parent().before(template);

        return false;
    });
    appliquerMasqueMontant(); 
}

Hope it will help someone !
