Limit the choices in an Excel drop down list, depending on the value in another cell.For example, select "Fruit" in cell B2, and "apple, banana, peach" appear in the drop down list in cell C2. In this dependent data validation example, if a country is selected from the first drop down, only that country's cities appear in the next column's drop down list. After you learn the basics, you can use the Excel IF function to make the selection more flexible.Description: When using the Dropdown Combo style attribute with validation java script to set other screen attributes according to the dropdown selection, the Dropdown Menu auto-populates values into other attribute fields.In this section we will discuss about select box validation in Java Script.Instead of just referring to the Produce range for the Produce Type drop down, the formula will check for an entry in the Item column.
To block changes to the first list, you can change the data validation formula, so the list doesn't work unless the second cell is empty.
