Categories and subcategories
Excel can be a good tool for filling questionnaires and for this purpose are often used structured tables where we keep the results. When the result is one of a few, in advance known, values the input is done by selecting it from the list. Sometimes there is a need to, after choosing value in the first list, affect the items that appear in the second. For example, choosing a category affects the display of related subcategories.
