When activating DHX Combo in a grid and then using a horizontal scroll bar for the grid while combo list is still open, combo box does not follow its original location on the grid ie, it does not scroll with the column it belongs to.
DHX Combo is static on the screen. Is this a known bug or is there a work around?
This is not a bug. Combo list has an absolute position.
You can try to close editor when grid scrolls:
