dropdown list length

Copper Contributor

I am trying to create a dropdown list which started off OK, I am adding the selections separated by a comma, however, I cannot add enough selections, there seems to be a character limit stopping me from adding any more items. is it possible to remove this limit so I can add more items to the list?

If you enter the values directly in the Source box, the total length cannot exceed 255 characters.

To get around this, enter the values in a column, one per cell. Then point to that range in the Source box.

@Hans Vogelaar thats great thanks, one more question if you could help please, I want a full column for the dropdown list which is OK but not the top heading, is it possible to do that?
