I'm currently working on a side menu that will list all pages in the relative section. I pretty much have this sorted apart from 1 small thing. We have 2 levels of dropdowns meaning there are an awful lot of links.
The LI that is active will have the class of .current_page_item
. I'm trying to work out a way of saying:
If the UL has a child LI containing .current_page_item
class then apply .side_open
class to the UL.
$(document).ready(function()
);

From what I understand, you want to style the direct parent if the li
is selected.
(Comment me if I'm wrong)
So, the following should be what you want to achieve:
(Done with some Javascript)
$(document).ready(function()
$('ul>li>ul>li').each(function()
if ($(this).hasClass('current_page_item'))
$(this).parent().addClass('side_open');
);
);
.side_open
background: #ddd;
.current_page_item
background: #bbb;

You can use .parentElement
property to access li
's ul
.
const linksArray = [...document.querySelectorAll('li')];
linksArray.forEach(link =>
link.onclick = function()
linksArray.forEach(link => link.classList.remove('current_page_item'))
this.classList.add('current_page_item')
this.parentElement.classList.add('side_open')
)
.current_page_item
background-color: aliceblue;
.side_open:before
content: 'I have side open class';
<ul>
<li>One</li>
<li>Two</li>
<li>Three</li>
<li>Four</li>

From what I understand, you want to style the direct parent if the li
is selected.
(Comment me if I'm wrong)
So, the following should be what you want to achieve:
(Done with some Javascript)
$(document).ready(function()
$('ul>li>ul>li').each(function()
if ($(this).hasClass('current_page_item'))
$(this).parent().addClass('side_open');
);
);
.side_open
background: #ddd;
.current_page_item
background: #bbb;

You can do it using jquery. It's very simple, using each loop, traverse and check for class in each LI and add .side_open
class in it's parent if that li has .current_page_item
class.
$(document).ready(function()
$('ul.main_ul>li>ul.sub_ul>li').each(function()
if($(this).hasClass('current_page_item'))
$(this).parent().addClass('side_open');
);
);
.side_open
background-color: red;
