When we say comma-separated-values, we mean that these values are manually entered as an input to the drop-down list while creating the same.

Now when you select a genre, the drop down list for the title selection will change depending on the genre. In the “Source” input type “=indirect($B$1)”, where $B$1 is the name of the cell with the movie genre input.Now select the cell where you’re going to select the movie title.This means your drop down list will now contain the values in the range you called “Type”. Select “Data Validation” in the “Data Tools” section.Select the cell where you’re going to select the genre.Repeat for the other three ranges containing the film titles and name them “Drama”, “Comedy” and “Horror” respectively.Select the first range containing the film genre list.We are going to let the user select from these three genres: Drama, Comedy and Horror. Ranges for each list of films within each genre.To do this we will need to set up a few items in our workbook. For example, we might want a user to be able to select from a film genre from a drop down list, then based on this we might want them to be able to select a film within that genre.

This means the drop down list will depend on some other value in the workbook and the available values in the drop down menu will change depending on this value. In this post we’re going to learn how to create a conditional drop down list in a cell.
