Append multiple To-do lists with javascript

I’m building a small to-do app.

Right now I can only add single tasks, and was wondering is there a way to add multiple to-do lists with their own tasks.

For example, list named Monday (with “buy groceries”), Tuesday (with wash dishes) etc.

I would also like to be able to delete single tasks, as I can now.

Thanks!

Here is my code:

    <body>
<div class="container">
  <header class="text-center text-light my-4">
    <h1 class="mb-4">To-do list</h1>
  </header>
  <form class="search text-center my-4">
    <label class="text-light"></label>
    <input
      class="form-control m-auto"
      type="text"
      name="search"
      autocomplete="off"
      placeholder="search tasks..."
    />
  </form>
  <ul class="list-group todos mx-auto text-light">
    <li
      class="list-group-item d-flex justify-content-between align-items-center"
    >
      <span>airline ticket reservation</span>
      <i class="far fa-trash-alt delete"></i>
    </li>
  </ul>

  <form class="add text-center my-4">
    <label class="text-light">Add new to-do item</label>
    <input
      class="form-control m-auto"
      type="text"
      name="add"
      autocomplete="off"
      placeholder="type here..."
    />
  </form>
</div>

<script src="app.js"></script>

…and my js code:

    const addForm = document.querySelector('.add');
    const list = document.querySelector('.todos');
    const search = document.querySelector('.search input');

    const generateTemplate = todo => {
        let html = `
        <li class="list-group-item d-flex justify-content-between align-items- 
     center">
            <span>${todo}</span>
            <i class="far fa-trash-alt delete"></i>
        </li>
        `
        list.innerHTML += html;
    }

    addForm.addEventListener('submit', e => {
        e.preventDefault();

        const todo = addForm.add.value.trim();
        if(todo.length){
            generateTemplate(todo);
            addForm.reset();
        }
    });

    //delete item

     list.addEventListener('click', e => {
        if(e.target.classList.contains('delete')){
            e.target.parentElement.remove();
        }
    });

    //search
    const filterTodos = term => {
         Array.from(list.children)
        .filter((todo) => !todo.textContent.includes(term))
        .forEach((todo) => todo.classList.add('filtered'))

        Array.from(list.children)
        .filter((todo) => todo.textContent.includes(term))
        .forEach((todo) => todo.classList.remove('filtered'))
     }

    //keyup
    search.addEventListener('keyup', () => {
         const term = search.value.trim();
        filterTodos(term);
    });
