Not receiving correct values from get_cell_from_pixel()

[DeadlyBrad42]

I am attempting to use get_cell_from_pixel() to implement dragging and dropping items from another list to add them to my grid, but I'm not getting back the values I expect.

I'm passing in a position relative to the document, but since get_cell_from_pixel() internally compares that against this.container.position() (and since my grid is in a div with position:relative) the calculation is off.

From the name, I had assumed the function worked from a pixel position relative to the document. I was wondering if there was a reason you used this.container.position() instead of this.container.offset()? Or if there is, is it possible to add in an optional argument that would use this.container.offset()? If it's a feature you'd be interested in adding, I could implement it and create the PR myself if you'd like.

@DeadlyBrad42 - apologies for the very long delay, but we're giving gridstack more attention now, and, as such, have added in the parameter you've recommended. getCellFromPixel now takes in an optional second parameter to use offset rather than position. Thanks for the suggestion to do this and recommendation to use offset.
