Implement a Dynamic 'Read More/Read Less' Text Expander

function createTextExpander(elementId, maxLength) {
  const element = document.getElementById(elementId);
  if (!element) {
    console.error(`Element with ID '${elementId}' not found.`);
    return;
  }

  const originalText = element.textContent.trim();
  if (originalText.length <= maxLength) {
    return; // No need to expand/collapse
  }

  const shortText = originalText.substring(0, maxLength);
  let isExpanded = false;

  const expanderButton = document.createElement('button');
  expanderButton.textContent = 'Read More';
  expanderButton.style.cssText = 'background: none; border: none; color: blue; cursor: pointer; text-decoration: underline; padding: 0; font: inherit;';

  const updateText = () => {
    element.textContent = isExpanded ? originalText : shortText + '...';
    expanderButton.textContent = isExpanded ? 'Read Less' : 'Read More';
  };

  expanderButton.addEventListener('click', () => {
    isExpanded = !isExpanded;
    updateText();
  });

  // Initial setup
  element.textContent = shortText + '...';
  element.parentNode.insertBefore(expanderButton, element.nextSibling); // Insert after the element
}

// Usage example:
