                                            ]

                                        ]
                                    ]


                                ]
                            ]

                        ]
                    ]
                ],
            ]
        ],
    ];

<li class="menu">
<a href="#menuLevel1" data-bs-toggle="collapse" aria-expanded="false" class="dropdown-toggle">
  <div class="">

Use recursive printing e.g.

<?php
function print_recursive($list){
    echo '<ul>';
    foreach($list as $item){
        echo '<li id="'.$item['id'].'">'.$item['text'];
        if( isset($item['children']) ){
            print_recursive($item['children']);
        }
        echo '</li>';
    }
    echo '</ul>';
}
print_recursive($list);
?>

And do not redefine svg objects on each use it, reuse defined objects instead e.g.
css

#svg_sources {
    position: fixed;
    top: 0;
    left: 0;
}

html

<html xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:svg="http://www.w3.org/2000/svg">
<head>
...
</head>
<body>
<div id="svg_sources">
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" x="0" y="0" width="0" height="0">
    <defs>
        <g id="menu_lines">
            <line x1="3" y1="0" x2="3.01" y2="0" />
            <line x1="8" y1="0" x2="21" y2="0" />
        </g>
        <g id="menu_icon" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="feather feather-list">
            <use xlink:href="#menu_lines" transform="translate(0,6)" />
            <use xlink:href="#menu_lines" transform="translate(0,12)" />
            <use xlink:href="#menu_lines" transform="translate(0,18)" />
        </g>
        <polyline id="menu_bullet" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="feather feather-list" points="9 18 15 12 9 6" />

php

function print_recursive($list){
    echo '<ul style="list-style-type:none">';
    foreach($list as $item){
        echo '<li id="'.$item['id'].'"><a href="javacript:void(0);"><svg width="24" height="24" viewBox="0 0 24 24"><use xlink:href="#menu_bullet" /></svg>'.$item['text'];
        if( isset($item['children']) ){
            print_recursive($item['children']);
        }
