Kendo UI - can I drag across the range slider by dragging the tooltip?

[qunel]

I'm using the range slider from Kendo UI for jQuery. It provides a drag handle and a tooltip that is not draggable. Is it possible to make it so that I can click and drag the tooltip to move the drag handle across the slider? The file for this is fairly dense and I am not the original author so I'm not sure what to provide for reference. I'm just wondering if it's possible even thought it's not covered in the Kendo docs as far as I can tell.

Could you please use this example to elaborate a bit more about the requirement? I am not sure I understand the idea with a draggable Tooltip.

Hello, I think it is possible to achieve the desired behavior by customizing the range slider component. Here's a general approach you can try:

1. Identify the relevant HTML elements: Inspect the rendered HTML of the range slider component using your browser's developer tools. Look for the HTML elements corresponding to the drag handle and the tooltip. These elements might have specific class names or IDs that can help you target them in your customization code.

2. Add event listeners: Using JavaScript/jQuery, add event listeners to the tooltip element for the desired events such as mousedown, mousemove, and mouseup. You can use jQuery's .on() method or vanilla JavaScript's addEventListener() to attach these listeners.

3. Implement the drag behavior: When the mousedown event is triggered on the tooltip, capture the initial mouse position. Then, as the mousemove event fires, calculate the distance the mouse has moved relative to the initial position. Update the position of the drag handle accordingly by modifying its CSS properties (e.g., left or transform: translateX()). Finally, on mouseup or mouseleave, remove the event listeners to stop the dragging behavior.

Here's a simplified example of how the code might look:

javascript
Copy
$(document).ready(function() {
  var $tooltip = $('#tooltip'); // Replace with the actual tooltip element selector
  var $dragHandle = $('#drag-handle'); // Replace with the actual drag handle element selector

  var isDragging = false;
  var initialMouseX = 0;
  var initialDragHandleLeft = 0;

  $tooltip.on('mousedown', function(event) {
    isDragging = true;
    initialMouseX = event.pageX;
    initialDragHandleLeft = parseFloat($dragHandle.css('left')) || 0;
  });

  $(document).on('mousemove', function(event) {
    if (isDragging) {
      var distance = event.pageX - initialMouseX;
      var newDragHandleLeft = initialDragHandleLeft + distance;
      $dragHandle.css('left', newDragHandleLeft);
    }
  });

  $(document).on('mouseup', function() {
    isDragging = false;
  });
});
