Update ngx-intl-tel-input package to 2.5.0

Add to your css code as below to give the box a fixed position(use !important to prevent override)
:host ngx-intl-tel-input ::ng-deep .country-dropdown{
left: 0px!important;
right: auto!important;
top: 100%!important;
transform: translateY(0px)!important;
bottom: auto!important;
}
SEE EXAMPLE

Your html page contains overflow style that's why it scroll up when type specific country, so you just need to unset it.

Submit dynamical form using JQuery

I´m not really sure I can do this, but it's worth the try.
I have a table with at least 10 items coming from a Mysql database. They are items for which you can bid. The idea is that every row (therefore, every item) has a button that can be clicked to enter the bid. This button opens a popup with a text field to enter the bid and a button to submit the form.
In order to identify the item the user is bidding for, I need its id, as well as the amount bid. The amount is really easy to get, but I´m struggling a lot with the item id.
Here is what I have:
$(document).ready(function(){
$(".show").click(function() {
$("#popup").show();
var $id = document.getElementsByClassName('show')[0].value;
console.log($id);
$("#jugador").val($id);
});
$("#close, #submit").click(function() {
$("#popup").hide();
});
});
#popup {
position: relative;
z-index: 100;
padding: 10px;
}
.content {
position: absolute;
z-index: 10;
background: #ccc;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
.overlay {
position: fixed;
top: 0;
left: 0;
width: 100vw;
height: 100vh;
background: #000;
z-index: 5;
opacity: 0.4;
}
<td><button class="show" id="bid" value="<?php echo $row2["id"];?>"><img src="pictures/bidIcon.png" width="30" height="30"></button></td>
/*Popup*/
<div id="popup" style="display: none;">
<div class="overlay"></div>
<div class="content">
<header>
<div id="close">✖</div>
</header>
<form name="form1" method="post" action="bid.php">
<fieldset>
<label for="bid">Bid:</label>
<input type="text" name="bidAmount" id="bidAmount" size="8" />
<input type="hidden" name="item" id="item" />
<input type="submit" tabindex="-1" style="position:absolute; top:-1000px">
</fieldset>
<footer>
<button type="button" id="submit">Bid Now</button>
</footer>
</form>
</div>
</div>
I´ve been trying for a while with no luck. I will always get the item id for the first element no matter in which button I click.
Is it feasible what I want? Is this the correct approach? Should I use a different one?
Thanks a lot in advance.

Just change this line:
var $id = document.getElementsByClassName('show')[0].value;
To this:
var $id = $(this).val();
The problem is that with document.getElementsByClassName('show')[0].value you are querying the first occurrence of the .show button. With $(this) instead you will be accessing the current clicked button.
JQuery binds the events to the target where you attach the event, so this will always be a reference to the target of the event. Using $(this) will create a jQuery object of the target element permitting to apply jQuery functions to the element.
As a side note, you shouldn’t duplicate the elements ids. Every id must be unique in the html document, so it will be a good practice to make that id different for each button.
Hope it helps.

To access the current div element's Id you can use the ($this), which refers to the current javascript object.
$("div").click(function(){
alert($(this).attr('id'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="1">Num 1</div>
<div id="2">Num 2</div>
<div id="3">Num 3</div>
<div id="4">Num 4</div>
Here in this example, i have created div's which when clicked return's the id of that div.

When you do it like this var $id = document.getElementsByClassName('show')[0].value; it will always take the first element having class="show".
Which will contain the first item hence always gives the id of first item.
So instead of doing it like that you can do it like this:
var $id = $(this).val();
This will select the current item on which user has clicked so will give the id of that item.

Extend check zone of a checkbox

I'm programming a menu with two checkboxes inside (mat-menu from Angular with native Javascript checkboxes) and if I'm not clicking exactly in the box that doesn't work, the menu is closing and the box not checked ...
By the way with the mat-menu I haven't found how to block the automatic closure of the menu when I click on it.
Do you have a solution ?
Capture of my menu
<!-- app.component.html -->
<div class="header">
<mat-toolbar color="warn">OpenLayers</mat-toolbar>
<div class="menu">
<button mat-button [matMenuTriggerFor]="menu">Marqueurs</button>
<mat-menu #menu="matMenu">
<button mat-menu-item>
<p>Piscines : <input type="checkbox" id="piscine" name="piscine" (change)="handleSelected1($event)"/></p>
</button>
<button mat-menu-item>
<p>Parkings : <input type="checkbox" id="parking" name="parking" (change)="handleSelected2($event)"/></p>
</button>
</mat-menu>
</div>
</div>

Here is an easy way of extending the checkbox zone using CSS :after pseudo-element:
p, label, button, .chk-extended{
position: relative;
}
/* The above element position will be taken as reference
for the pseudo-element absolute positioning below:
*/
.chk-extended:after,
.chk-over-elm:after{
position: absolute;
content: '';
border: 1px dotted gray; /* For visibility */
/* The below can be adjusted */
top: -0.5em;
bottom: -0.5em;
left: -0.5em;
right: -0.5em;
}
Regular:<input type="checkbox" />
<br><br>
Extended:<input class='chk-extended' type="checkbox" />
<br><br>
<label>Extended on label:<input class='chk-over-elm' type="checkbox" /></label>
<br><br>
<button>Extended on button:<input class='chk-over-elm' type="checkbox" /></button>
<br>
<p>Extended on p:<input class='chk-over-elm' type="checkbox" /></p>
Note that I used p, label, button as examples in my snippet, but it can work with anything else.
Also, you may need to use !important on the CSS rules to override rules that are already set.
Hope it helps.

Open browser-standard colorpicker with javascript without type=color

Does anyone knows a javascript only way to open the browser-standard colorpicker, without using a html field? so i want a javascript what does exactly the same a a click on the html input color field.
Bart

You are going to have to use the input field, you can just hide it off the page. Issue here is the fact that the color dialog requires a click in browsers in order to open up the color dialog. It will not work if you just call click()
document.getElementById("xxx").addEventListener("click", function() {
document.getElementById("c").focus();
document.getElementById("c").value = "#FFCC00";
document.getElementById("c").click();
});
.hidden {
position: absolute;
left: -10000px;
top: auto;
width: 1px;
height: 1px;
overflow: hidden;
}
<input type="color" id="c" tabindex=-1 class="hidden">
<input type="button" id="xxx" value="Click Me!">

Here's a good old "hover-hack" solution that works even in MS Edge:
<input type="color" style='opacity:0;width:100px;position:absolute;'/>
<button>clickme</button>
then bind onchange to the colro element

Weird event binding issue on FF and Chrome - only on first click

This is on my plugin page on Git and I have two interactive demo in the web page. In one of the demo page, I have a small dialog that opens when you click on a div.
The weird issue is that this dialog is getting opened when I click on the top title that says attrchange beta . This happens only if the first click is on the title attrchange beta, clicking any other element in page fixes this issue.
The plugin page http://meetselva.github.io/attrchange/ [Fixed, use the below URL to see the problem]
http://meetselva.github.io/attrchange/index_so_issue.html
Below is the code,
<!-- The title -->
<h1 id="project_title">attrchange <span class="beta" style="text-decoration: line-through;" title="Almost there...">beta</span></h1>
<!-- Main dialog that has link to the sub-dialog -->
<div id="attributeChanger">
<h4 class="title">Attribute Changer</h4>
<p>Listed below are the attributes of the div:</p>
<div class="attrList"></div>
<div class="addAttribute text-right">add new attribute</div>
</div>
<!-- Sub-dialog -->
<div id="addOrmodifyAttr" title="Add/Modify Attribute">
<h4 class="title">Add/Modify Attribute</h4>
<p><b>Attr Name</b> <input type="text" class="float-right attrName"></p>
<p><b>Attr Value</b> <input type="text" class="float-right attrValue"/></p>
<div class="clear"> </div>
<button type="button" class="float-right close">Close</button>
<button type="button" class="float-right update">Update</button>
<div class="clear"></div>
</div>
JS:
var $attributeChanger = $('#attributeChanger');
var $attrName = $('.attrName', '#addOrmodifyAttr'),
$attrValue = $('.attrValue', '#addOrmodifyAttr'),
$attrAMUpdate = $('.update', '#addOrmodifyAttr');
//Handler to open the sub-dialog
$attributeChanger.on('click', '.addAttribute', function () {
$attrName.val('').removeClass('nbnbg');
$attrValue.val('');
$('#addOrmodifyAttr, #overlay').show();
});

The problem is the CSS applied to your #attributeChanger div.
If you look at the CSS applied to it:
#attributeChanger {
background-color: #FEFFFF;
border: 1px solid #4169E1;
color: #574353;
font-size: 0.9em;
margin: 10px;
min-height: 50px;
min-width: 150px;
opacity: 0;
padding: 2px;
position: absolute;
top: -200px;
z-index: 1;
}
You'll notice that the position is absolute, and it's positioned over your logo. So what you're clicking is actually your #attributeChanger div.
To fix it, you can hide #attributeChanger using display: none;, then use $('#attributeChanger').show(); in jQuery when it comes into actual view.

The pop up is showing because this code is running:
}).on('click', '.addAttribute', function () {
$attrName.val('').removeClass('nbnbg');
$attrValue.val('');
$('#addOrmodifyAttr, #overlay').show();
This is because the DIV with the class addAttribute is over the title DIV.
You can either move the 'addAttribute' DIV, or remove the last line of that onclick function.

That is because you element is hover your title and detect the click on himself and open(i don't know why it open, i didnt examine your entire code). But when you click anywhere else, your code is changing his position so it is not over the title.
The easiest fix is to change you #attributeChanger CSS top to -100px (that's the value when you click on the document) OR add a display : none.
EDIT : Axel answer show what I mean by "element is hover your title".
