Last option in select box (coro type)

Hi all,
I would like to know why is inserted by default the text of the cell you have selected for editing as the last option of the “select box” (coro) of this cell and whether exist or not the way of avoiding this behavior.

The select box loading for each cell of the column is done from js.

Thanks anyway.

You should pass option value as value of the cell

<cell xmlcontent="true">1<option value="1">The first</option><option value="2">The second</option></cell>
