Unable to navigate a simulated scrollbar

As someone who is new to web development, I am embarking on the journey of building a UI Grid that can effectively display a large amount of data. My goal is to implement a scrollbar that allows for horizontal scrolling across approximately 1,000,000 data points. The grid should load a 20x20 segment of data and then lazily load the next page as the scrollbar is moved.

Although I have successfully displayed the horizontal scrollbar on the screen, I am struggling to make it actually scroll. I am drawing inspiration from fattable (https://github.com/fulmicoton/fattable) and seeking guidance on making my scrollbar functional like in this example: http://jsdo.it/jpez/Q7g0

If anyone has tips on how to make my horizontal scrollbar scroll when clicked and dragged, I would greatly appreciate your assistance. Currently, it remains stationary despite attempts to move it.

Answer №1

Your stacking order for elements needs adjustment. To fix this issue, either add z-index: 1 to your scrollbar or rearrange the order of .signal-viewport, .signal-h-scrollbar, and .signal-v-scrollbar like so:

<div class="signal-viewport">...</div>
<div class="signal-h-scrollbar">...</div>
<div class="signal-v-scrollbar">...</div>

For more information on how z-index works, you can visit this link.
