In Google Chrome, how do I drag things around on a touchscreen Android device? Clicking and dragging something from a webpage is easy from a PC. For example, the bar in the screenshot below can be dragged by holding the left mouse button and moving the mouse simultaneously:



My attempts for doing the same in chrome in android:


I tried to move it by dragging but the page moves when I do it. 
When I hold over it for some time, a nearby text gets selected and I'm presented with the options to copy, cut , paste etc the selected text.
Tried to attempt both ways from the stock android browser to see if was a problem in chrome, but failed again.


So, How do I do it in chrome in android?

I'm using chrome 44.0.2403.128 with android 4.4.2
You can do it with just a mouse (or pen) on pages where it is supported. I tested it with a plain USB mouse on my Moto G running Android 4.4.4.

I resized area for post with bottom right striped triangle on "dotaz nebo sdělení" field with mouse. See this tested page.

Or you can pair an ordinary Bluetooth mouse with your device. Probably any modern Android device includes Bluetooth mouse support.
