I am in need of assistance to implement an accordion menu with unique picture icons for each item on the left and a toggle icon (such as + or a chevron) on the right side.

Visually, I would like it to resemble this design (https://codepen.io/kathykato/pen/MoZJom), but with the addition of a custom icon on the left of each item to represent its content.

I am using SquareSpace, however, since SquareSpace does not offer an accordion menu block/widget, I plan to manually input the code. Despite spending hours experimenting with different code snippets and trying to modify existing examples, this is my first attempt at creating an accordion menu and I am facing difficulties.

Your help would be greatly appreciated!

Below is the example code structure that I aim to achieve, but with the inclusion of a unique picture icon on the left:

HTML:

<div class="container">
