Losing my mind converting html menu to wp_list_pages

I’m having a tough time converting code from my html navigation to wordpress wp_list_pages. Can anyone help me translate this? I can’t figure out how to match the css with the php code.

I have page: “About Us” with a child page “Locations”
and page: “Careers” with no child page.

I substituted ‘<‘ and ‘>’ with ‘(‘ and ‘)’ to make the code show up in the forum.

(ul)
(li) class=”page_item page-item-2″)(a href=”https://website.com/?page_id=2&#8243; title=”About Us”)About Us(/a)
(ul)
(li class=”page_item page-item-13″)(a href=”https://website.com/?page_id=13&#8243; title=”Locations”)Locations(/a)(/li)

(/ul)
(/li)
(li class=”page_item page-item-8″)(a href=”https://website.com/?page_id=8&#8243; title=”Careers”)Careers(/a)
(ul)
(li class=”page_item page-item-12″)(a href=”https://website.com/?page_id=12&#8243; title=”Benefits”)Benefits(/a)(/li)
(/ul)
(/li)
(/ul)

You have a button above this text input area that says “CODE”.
Use it next time, that’s why they made it for you: to enable you to post normal code!

Sorry, I’ll use it next time.

I don’t understand how do you think that a menu linking to existing physical html files can be “converted” to a WP function/template tag.

If you want to use Pages written in WordPress instead of those existing files – just create all those pages in the proper child-parent relationship in your WP admin – and the template tag will do the work for you displaying the list of Pages as menu items.

My html website uses Javascript and this code to generate drop-down menus.
The html version is at tech.donwatford.com.

I have created the supporting pages in WP, I just want them to work with my existing menu system.

btw, can somebody remove the code from my original post? I posted it incorrectly.
