Elements according to active LI

To hide elements based on the active list item (LI) position using jQuery, you can use the .slice() and .hide() functions. Here's an example code snippet that demonstrates this:

$(document).ready(function() {
  // Get all the LI elements
  var listItems = $('ul li');

  // Attach click event handler to the LI elements
  listItems.click(function() {
    // Get the index of the clicked LI element
    var activeIndex = $(this).index();

    // Calculate the start and end indices of the elements to show
    var startIndex = Math.max(0, activeIndex - 2);
    var endIndex = Math.min(listItems.length - 1, activeIndex + 2);

    // Hide all LI elements
    listItems.hide();

    // Show the elements within the start and end indices
    listItems.slice(startIndex, endIndex + 1).show();
  });
});

you have a

element containing the list items (
• ). The code attaches a click event handler to each list item. When a list item is clicked, it calculates the start and end indices of the elements to show, based on the clicked item's index. Then, it hides all list items and shows only the elements within the specified range using the .slice() function.
