First I started by using data validation and adding a list to more than 5000 cells, but the list contains a lot of values so scrolling through it got difficult each time selecting from the list takes a lot of time. So I read many forums and used Combobox instead to autocomplete what we typed and this saved my time a lot, but the problem now is I want it to be used on all the rows in One column, I cannot copy and paste the combobo each time on every cells. is there any short cut by using VBA or anything. Kindly help me with the same it's urgent.
