How can I select multiple items that are generated in real time with JS?

I'm trying to get the user preferences, which will be 5 or 10, I haven't defined that yet.

But the options that will be shown in the first instance are the following (They are being retrieved in a JSON through a WebApi, but for example, I put what I get):

<?php
    $json2 = '{"0":{"Id_Categoria":2,"Imagen":"https:\/\/res.cloudinary.com\/dcksq4ylu\/image\/upload\/v1631725779\/neb2ymglgqmmaexgkcez.png","Nombre":"Vinos y licores","Activo":1,"demanda":148},"1":{"Id_Categoria":1,"Imagen":"https:\/\/res.cloudinary.com\/dcksq4ylu\/image\/upload\/v1631725152\/umk40bjvcxpoc08bcu7q.png","Nombre":"Calzado","Activo":1,"demanda":52},"2":{"Id_Categoria":21,"Imagen":"https:\/\/res.cloudinary.com\/dcksq4ylu\/image\/upload\/v1631726499\/ciperp26mazrm7wao9fs.png","Nombre":"Carnicerias","Activo":1,"demanda":9},"3":{"Id_Categoria":22,"Imagen":"https:\/\/res.cloudinary.com\/dcksq4ylu\/image\/upload\/v1631726499\/ciperp26mazrm7wao9fs.png","Nombre":"Cafeterias","Activo":1,"demanda":7},"4":{"Id_Categoria":25,"Imagen":"https:\/\/res.cloudinary.com\/dcksq4ylu\/image\/upload\/v1631726499\/ciperp26mazrm7wao9fs.png","Nombre":"Taquerias","Activo":1,"demanda":7},"5":{"Id_Categoria":3,"Imagen":"https:\/\/res.cloudinary.com\/dcksq4ylu\/image\/upload\/v1631725966\/q5cczltjedz1wg1iat8f.jpg","Nombre":"Articulos (c\u00f3mputo)","Activo":1,"demanda":6},"6":{"Id_Categoria":24,"Imagen":"https:\/\/res.cloudinary.com\/dcksq4ylu\/image\/upload\/v1631726499\/ciperp26mazrm7wao9fs.png","Nombre":"Tintorerias","Activo":1,"demanda":6},"7":{"Id_Categoria":4,"Imagen":"https:\/\/res.cloudinary.com\/dcksq4ylu\/image\/upload\/v1631726499\/ciperp26mazrm7wao9fs.png","Nombre":"Paletass y helados","Activo":1,"demanda":5},"8":{"Id_Categoria":5,"Imagen":"https:\/\/res.cloudinary.com\/dcksq4ylu\/image\/upload\/v1631726157\/qad9inm54ma56s2s4tta.png","Nombre":"Comercios de Pintura","Activo":1,"demanda":5},"9":{"Id_Categoria":23,"Imagen":"https:\/\/res.cloudinary.com\/dcksq4ylu\/image\/upload\/v1631726499\/ciperp26mazrm7wao9fs.png","Nombre":"Ferreterias","Activo":1,"demanda":4}}';
    
    echo($json2);
?>

I am retrieving this JSON with ajax in the following way (I think it is the simplest):

$("#Abrir").click(function() {
        //$(document).ready(function(){
        //invocar json desde jquery
        $("#Class2 div").remove();
        $.ajax({
            url: "prueba.php",
            //Datos que se envian a prueba.php
            data: {},
            //Cambiar a type: POST si necesario
            type: "GET",
            // Formato de datos que se espera en la respuesta
            dataType: "json",
            success: function(datos) {
                //Información que llega
                var salida = "";
                $.each(datos, function(i, val) {
                    salida += "<div class='box Ide_Cat box" + val.Id_Categoria + "' id=" + val
                        .Id_Categoria + ">";
                    salida += "<img src='" + val.Imagen + "' alt = '" + val.Id_Categoria +
                        "'>";
                    salida += "<h2 id='Nom'>" + val.Nombre + "</h2>";
                    salida += "<input type='hidden' Id ='Id_cat'value='" + val
                        .Id_Categoria + "'>";
                    salida += "</div>";
                });
                $("#Class2").append(salida);
            },
            error: function(jqXHR, status, error) {
                console.log("La solicitud a fallado: " + error);
                console.log("La solicitud a fallado: " + jqXHR);
                console.log("La solicitud a fallado: " + status);
            },
            complete: function(jqXHR, status, error) {
                //alert("Transaccion completa");
            }
        });
    });

and they're getting in here:

<div class="container-box " id="Class2">
  <div id="box" class="box">
    <input type="hidden" value="12">
  </div>
</div>
<div class=" row justify-content-center">
  <a href="#" id="a-submit">Enviar selecciones</a>
</div>

To get multiple selections of categories (because that's what I think would work) displayed I have found several solutions but they don't work as I think I require, because the following: on a click event it does not retrieve the Id of the category the user is selecting but retrieves the Id_ of the first category only, regardless of whether the last one was selected:

var imagenes = document.querySelectorAll('#Class2');
    var titular = document.querySelector('#Id_cat');
    var Id_cts = new Array();
    $("#Abrir").ready(function() {
        for (var i = 0; i < imagenes.length; i++) {
            imagenes[i].addEventListener('click', function(){
                var ide = ('#Id_cat').val();
                var nombre = $('#Nom').val();
                console.log("El id de la categoria seleccionada es: "+ ide + " y el nombre es: " + nombre)
                var texto = "nombre";
            });       
        }
    });

And the following code only works by pressing the CTRL button although it still only retrieves the id_category of the first category regardless if you select the last one:

var selected_rows = []
    $("#Class2").click(function() {
        let clicked_row = $(this)
        if (clicked_row.hasClass('selected')) {
            clicked_row.removeClass('selected')
        } else {
            clicked_row.addClass('selected')
        }
    });

    $('#a-submit').click(function() {
        data = []
        selections = $('.selected')
        selections.each((index, element) => {
            let row_content = {
                Id_cat: $(element).find('#Id_cat').val(),
                lastname: $(element).find('#Nom').text(),
            }
            data.push(row_content)
        })
        console.log("Your selections:", data)
    })

In a nutshell:

Based on the JSON categories.

1-. I want to get the user's preferences

2.- There must be at least 5 or more categories selected.

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
