I have an EO:Grid with a custom column (Dropdown). I have coded as seen in your sample code.

When the page is used from a PC browser (Chrome, FF and others) there is no problem.

When I do the same from a tablet or phone device, I can select values from the dropdown, but if I scroll in the grid, it is no longer possible to select values from the dropdown, it is blocked after scrolling.

I am using EO.Web 18.2.74.0

The problem is easy reproducable here: http://test.fscrm.ch/eogridtest.aspx

It is important to get a solution for that. Thanks.

Hi,

Which type of device do you use? We tested it on an Andriod phone and it seems to work fine.

Thanks!

Hi,

We tested with iPad iOS 9.3.5 and it still works fine. What version/browser do you use?

Thanks!
