jQuery sortable in nested element

I have a list with categories and questions (which can both be added dynamically), at the moment I am able to sort the categories using jQuery sortable, but not the questions underneath the categories.
I've tried just adding another .sortable function on the question wrap element but it is not responding at all.
My code at the moment:
// HTML template for new fields
const template = `
<div class="row sortwrap">
<div class="col-md-8">
<input type="text" name="category[]" placeholder="" class="form-control name_list catinput" />
<i class="mdi mdi-sort dragndrop"></i>
<div class="questionlist questionwrap">
<div class="row">
<div class="col-md-8">
<button class="btn btn-success questionbutton">Extra vraag</button>
<input type="text" name="question[]" placeholder="1. Voeg een vraag toe" class="form-control name_list questioninput" />
</div>
<div class="col-md-4">
</div>
</div>
</div>
</div>
<div class="col-md-4">
<button id="addcategory" class="btn btn-danger btn_remove removebutton">X</button>
</div>
</div>`;
const vraagTemplate = `
<div class="row" id="question">
<div class="col-md-8">
<input type="text" name="question[]" class="form-control name_list questioninput" />
</div>
<div class="col-md-4">
<button class="btn btn-danger btn_remove">X</button>
</div>
</div>`;
// Count numbers and change accordingly when field is deleted
function updatePlaceholders() {
// Sortable code
// $('#dynamic_field').sortable( "refresh" );
let df = $('#dynamic_field');
df.find('input[name^=cat]').each(function(i) {
$(this).attr("placeholder", i + 1 + ". Voeg een categorie toe");
});
df.find('.sortwrap').each(function(i) {
$(this).attr("id", i + 1);
});
df.find('.questionlist').each(function() {
$(this).find('input[name^=qu]').each(function(i) {
$(this).attr("placeholder", i + 1 + ". Voeg een vraag toe");
});
});
}
// Append question template
$('#dynamic_field').on('click', '.questionbutton', function() {
let $ql = $(this).closest('.questionlist');
$ql.append($(vraagTemplate));
updatePlaceholders();
});
// Delete
$('#dynamic_field').on('click', '.btn_remove', function() {
$(this).closest('.row').remove();
updatePlaceholders();
});
$('#addcategory').on('click', function() {
let t = $(template)
$('#dynamic_field').append(t);
updatePlaceholders();
});
$(function() {
$('#addcategory').trigger('click');
$('#question').sortable();
$('#dynamic_field').sortable({
cancel: '.questionwrap',
placeholder: "ui-state-highlight"
});
});
This is my sortable code:
$(function() {
$('#addcategory').trigger('click');
$('#question').sortable();
$('#dynamic_field').sortable({
cancel: '.questionwrap',
placeholder: "ui-state-highlight"
});
#question is the wrap of my question list and #dynamic_field is the wrap of my category element (the questions are also inside this element).
How can I make my questions also sortable? And also only make then sortable inside their parent div (so I can't drag a question from one category to the other but only within its own category).

One of the first thing I have noticed about your code is that the ID is repeated for each creation of a dynamic element. This will cause a lot of issues when you have 6 #question elements. This can be addressed by adding the ID to the element when it's created and creating a unique ID. For example, if there are 0 #questions then you can count that and add 1.
<div id="question-1"></div>
<script>
var id = $("[id|='question']").length + 1;
</script>
In this, id would be 2. there is one element that contains "question" and the |= selector will look for that before the - in a ID name. Can also use ^= selector.
Making use of handle will help a lot too. This will help allow proper sorting of nested items versus their parents. Also containment is helpful here too unless you want to move them between lists.
Consider the following code. It's a little clunky and I hope you can see what I am referring to.
$(function() {
function makeSortable(obj, options) {
console.log("Make Sortable", obj);
obj.sortable(options);
obj.disableSelection();
}
function updateSort(obj) {
console.log("Update Sortable", obj);
obj.sortable("refresh");
}
function addQuestion(q, c) {
console.log("Add Question", q, c);
var makeSort = $("[id|='question']", c).length === 0;
var question = $("<div>", {
class: "question",
id: "question-" + ($("div[id|='question']", c).length + 1)
});
question.append($("<div>", {
class: "col-md-8"
}).html(q));
question.append($("<div>", {
class: "col-md-4"
}).html("<button class='btn btn-danger btn-remove'>X</button>"));
question.appendTo($(".catcontent", c));
console.log(makeSort, question, c);
if (makeSort) {
makeSortable($(".catcontent", c), {
containment: "parent",
items: "> div.question"
});
} else {
updateSort($("[id|='question']", c).eq(0).parent());
}
}
function makeCategory(name) {
console.log("Make Category", name);
var makeSort = $("[id|='category']").length === 0;
var cat = $("<div>", {
class: "category ui-widget",
id: "category-" + ($("[id|='category']").length + 1)
});
cat.append($("<div>", {
class: "cathead ui-widget-header"
}).html(name + "<i class='btn btn-add-question'>+</i>"));
cat.append($("<div>", {
class: "catcontent ui-widget-content col-md-8"
}));
cat.appendTo($("#cat-wrapper"));
if (makeSort) {
makeSortable($("#cat-wrapper"), {
handle: ".cathead",
items: "> div.category"
});
} else {
updateSort($("#cat-wrapper"));
}
}
$('#addcategory').on('click', function() {
let t = $(template);
$('#dynamic_field').append(t);
updatePlaceholders();
});
$(".categorybutton").click(function(e) {
e.preventDefault();
makeCategory($(".catinput").val());
$(".catinput").val("");
});
$(".catwrap").on("click", ".btn-add-question", function(e) {
e.preventDefault();
var resp = prompt("Question to Add:");
addQuestion(resp, $(this).parent().parent());
});
});

I can´t remove the last item of array

I can remove any item of array unless the last one. I also use angularjs to show information in the view. I don´t know what is happening with the last item of this array. Please, anyone can help me?
Here is HTML:
<div class="row">
<div class="col-md-12">
<h4><strong>Documento {{index + 1}} de {{documentos.length}}:</strong> {{documentos[index].nome}}</h4>
<iframe style="background: #ccc;" ng-show="exibirPreview" frameborder="0" ng-src="{{versaoLink}}" width="100%" height="300px"></iframe>
<div class="alert alert-warning" ng-hide="exibirPreview">
#Html.Raw(Resources.Dialog.SignDocuments.TypeDocumentCanNotPreDisplayed)
</div>
<hr />
<div class="pull-right btn-row" ng-show="documentos.length > 1">
<button class="btn btn-default" type="button" ng-click="RemoveDoc(index)"><i class="fa fa-fw fa-times"></i> #Resources.Common.RemoveDocList</button>
</div>
</div>
</div>
Here is js/angularjs
$scope.documentos = [
{nome:"document1", chave: "8F65579E3737706F", extensao:".pdf"},
{nome:"document2", chave: "8F65579E3730007F", extensao:".pdf"},
{nome:"document3", chave: "8545579E3737706F", extensao:".pdf"},
{nome:"document4", chave: "8555579E3730007F", extensao:".pdf"}
]
$scope.ViewLink = function () {
var versao = $scope.documentos[$scope.index];
$scope.exibirPreview = versao.extensao == ".pdf" || versao.extensao == ".txt";
if (!$scope.exibirPreview) {
$scope.versaoLink = '';
} else {
$scope.versaoLink = '/Documento/VersaoView?chave=' + versao.chave;
}
};
$scope.ViewLink();
$scope.RemoveDoc = function (index) {
$scope.documentos.splice(index, 1);
$scope.ViewLink();
};
Or Plunker

In your HTML you are preventing the deletion of the last element:
<div class="pull-right btn-row" ng-show="documentos.length > 1">
<!-- -->
</div>
documentos.length > 1 means "hide when it reaches one item in the array".
It should be documentos.length == 0.
It's either this or your index value starts from 1 and not from 0.

The simplest solution would be to change your remove function to take in the document instead of the index. Try this:
$scope.RemoveDoc = function(document) {
var index = $scope.documents.indexOf(document);
$scope.documents.splice(index, 1);
}
in view:
<button class="btn" type="button" ng-click="RemoveDoc(document)">Delete</button>

opening the text box is working only first time api call, second time text box is not getting open

I have a question & aanswer module, on clicking to write an answer to a question, first time the answer box opens and after submitting the answer, When I again open the answer text box, It doesn't opens.
My HTML Code
<li class="question answered" id="unansweredBlock" ng-if="unanswered_Que.length !==0">
<div class="qstn" id="qBlock-{{questions.question_id}}" ng-repeat="questions in unanswered_Que">
<span class="qstn-icon qicon"></span>
<div>
<div class="qmeta">
<div>Asked by {{questions.asked_by}} on {{questions.asked_at}}</div>
</div>
<h4>{{questions.question}}</h4>
</div>
<div id="ansId-{{questions.question_id}}" class="qbottom">
Write your answer
</div>
<hr class="seperator">
<div class="sendAnswer" ng-show="selectedAnswerPanel== $index" ng-hide="selectedAnswerPanel != $index">
<div class="sndAnswer">
<form action="">
<div class="form-group">
<h5>EXPERTS ANSWER</h5>
<textarea id="answer_Text{{$index}}" ng-model="answerText" placeholder="Write your comments" class="form-control"></textarea>
</div>
<div class="form-group">
<button type="submit" class="btn btn-default" ng-click="answer_Que(questions,'answer_Text'+$index);">Send your Answer</button>
</div>
</form>
</div>
</div>
</div>
My JS Code
$scope.showHideAnswerPanel = function(index) {
if ($rootScope.isUserLoggedIn == true) {
if ($scope.selectedAnswerPanel == index) {
$scope.selectedAnswerPanel = -1
} else {
$scope.selectedAnswerPanel = index;
}
} else {
$rootScope.openLogin();
}
};
and another function is:-
$scope.answer_Que = function(unanswered_Que, answerExp) {
var requestParam = {
"uid": lclStorage.get('userData')[0].uid,
"token_key": lclStorage.get('userData')[0].token_key,
"question_id": unanswered_Que.question_id,
"answer": $("#" + answerExp).val()
}
appServices.doAPIRequest(appSettings.appAPI_ci.answeraQue.sendAnswer, requestParam, null, 'userData')
.then(function(data) {
});
if ($scope.unanswered_Que.length == 1) {
$("#answer_Text").val(" ");
$(".sendAnswer").hide();
$("#unansweredBlock").remove();
} else if ($scope.unanswered_Que.length > 1) {
$("#answer_Text").val(" ");
$(".sendAnswer").hide();
$("#qBlock-" + unanswered_Que.question_id).remove();
} else {
$("#answer_Text").val(" ");
$(".sendAnswer").hide();
}
};

How to get the value of a particular input field using id in the html templates

I have two div html elements with different id and here I am using spinner. Whenever values in the spinner input changes alert box will be displayed.
HTML code
<div id="accordion2" class="panel-group" style="display: block;">
<div id="accordion2" class="panel-group">
<div id="Tea">
<div class="spinner Tea input-group ">
<input type="text" id = "servings" class="form-control input- sm" value="Tea"/>
<div class="input-group-btn-vertical">
<button class="btn Tea btn-default">
<i class="fa fa-caret-up"></i>
</button>
<button class="btn Tea btn-default">
<i class="fa fa-caret-down"></i>
</button>
</div>
<h4 id="energy" class="Tea"> Tea </h4>
</div>
<div id="Coffee">
<div class="spinner Coffee input-group ">
<input type="text" id = "servings" class="form-control input-sm" value="Coffee"/>
<div class="input-group-btn-vertical">
<button class="btn Coffee btn-default">
<i class="fa fa-caret-up"></i>
</button>
<button class="btn Coffee btn-default">
<i class="fa fa-caret-down"></i>
</button>
</div>
<h4 id="energy" class="Coffee">Coffee</h4>
</div>
</div>
</div>
JQuery code
$(function(){
$('.spinner:first-of-type input').on('click', function() {
$('.spinner:first-of-type input').val(parseInt($('.spinner:first-of-type input').val(), 10) + 1);
var val = $('.spinner:first-of-type input').val();
changeValues(val);
});
$('.spinner:last-of-type input').on('click', function() {
$('.spinner input').val( parseInt($('.spinner input').val(), 10) - 1);
});
function changeValues(value){
alert($('#energy').attr('class').split(' '));
};
});
But in the alert box whenever I click the spinner up arrow only Tea is displayed.
what I expect is when the spinner is clicked from Tea div tea should be displayed and when from coffee , coffee should be displayed.Please help me out

I'm not sure I totally got what you are trying to do, but it seems to me that you want to increment and decrement number of beverage cups on up/down buttons click. For this you would better modify mark up a little (remove duplicated ids, add classes for convenience). And I may look like this then:
$(function() {
$('.spinner').on('click', '.servings', function(e) {
$(this).val(parseInt($(this).val() || 0, 10) + 1);
var val = $(this).val();
changeValues.call(e.delegateTarget, val);
})
.on('click', '.up', function(e) {
$(e.delegateTarget).find('.servings').val(function() {
return ++this.value;
});
})
.on('click', '.down', function(e) {
var $input = $(e.delegateTarget).find('.servings');
if (+$input.val() > 1) {
$input.val(function() {
return --this.value;
});
}
});
function changeValues(value) {
var type = $(this).find('.energy').data('type');
alert(type);
};
});
Demo: http://plnkr.co/edit/9vXC0RipxkzqhXrHJAKD?p=preview

try this:
$(function () {
$('.spinner').each(function () {
var $el = $(this),
$buttons = $el.find('button'),
$h4 = $el.find('h4'),
input = $el.find('input').get(0);
function showAlert() {
alert($h4.get(0).className);
}
$buttons.eq(0).on('click', function (event) {
event.preventDefault();
input.value = (parseInt(input.value, 10) || 0) + 1;
showAlert();
});
$buttons.eq(1).on('click', function (event) {
event.preventDefault();
input.value = (parseInt(input.value, 10) || 0) - 1;
});
});
});
