问题
I am trying to solve one issue since days and finally understood that I will not succeed without help ... I want to do a common thing that we see on internet everyday : be able to click on a table row in order to show more details. But here more details does not mean a block of text but child rows which have same shape as parent rows.
Here is an example of HTML table :
<table class="collapse table">
<tr>
<th>Age</th>
<th>Sex</th>
<th>Name</th>
<th>From</th>
</tr>
<tr class="parent">
<td>100</td>
<td>M</td>
<td>Dodo</td>
<td>UK</td>
</tr>
<tr class="cchild">
<td>10</td>
<td>M</td>
<td>Child</td>
<td>UK</td>
</tr>
<tr class="cchild">
<td>10</td>
<td>M</td>
<td>Child</td>
<td>UK</td>
</tr>
<tr class="cchild">
<td>10</td>
<td>M</td>
<td>Child</td>
<td>UK</td>
</tr>
<tr class="parent">
<td>100</td>
<td>M</td>
<td>Dodo</td>
<td>UK</td>
</tr>
<tr class="cchild">
<td>10</td>
<td>M</td>
<td>Child</td>
<td>UK</td>
</tr>
<tr class="cchild">
<td>10</td>
<td>M</td>
<td>Child</td>
<td>UK</td>
</tr>
<tr class="cchild">
<td>10</td>
<td>M</td>
<td>Child</td>
<td>UK</td>
</tr>
The number of child and parent is flexible, I would like a example which manage flexible with that characteristic . Child rows will have to be closed when the page is load, and expand only if the user click on the parent one. If it is also possible I would like to add an icon which indicates to user the ability to click on a row ( basically a "+" and a "-" ), but not a simple string, a real icon.
I have seen and followed many examples, but no one of them did the job perfectly and tried to modify examples ... no success. Most of them were examples based on Datatables and I do not want to use it.
Can you help me please ? I know that my question is quite full and I am asking for a big part of work, but did not find a complete example to do what I want using HTML,CSS,Javascript only.
Thank you.
Edit after Andrei Gheorghiu's answer :
I would like finally being able to click only on the icon rather than on the entire row, I have others buttons on the same row, and if I click on, it actives the child opening. So what I did, waiting a better solution :
HTML : Changing "tr" to a specific "td" class and add the icon line within this "td.toto" class.
JS :
$('table').on('click', 'td.toto', function(){
console.log("Check click works: ");
$(this).closest('tbody').toggleClass('open');
});
So is it possible to follow your solution structure, but only change the click target ? By better solution, I meant, to click only on the icon rather than on the entire "td" now.
Thank you.

You will need to wrap each group of parent + children in a <tbody> for this and use a small script to toggle a class name on this parent <tbody>. Here's an example:
$('table').on('click', 'tr.parent .fa-chevron-down', function(){
$(this).closest('tbody').toggleClass('open');
});.parent ~ .cchild {
display: none;
}
.open .parent ~ .cchild {
display: table-row;
}
.parent {
cursor: pointer;
}
tbody {
color: #212121;
}
.open {
background-color: #e6e6e6;
}
.open .cchild {
background-color: #999;
color: white;
}
.parent > *:last-child {
width: 30px;
}
.parent i {
transform: rotate(0deg);
transition: transform .3s cubic-bezier(.4,0,.2,1);
margin: -.5rem;
padding: .5rem;
}
.open .parent i {
transform: rotate(180deg)
