#USE IN FORMULA DROP DOWN BOX EXCEL 2016 HOW TO#
You can write the formula directly, however saving it in a name first makes it re-usability.Īlso see the related article Excel’s Dynamic Charts: A Tutorial On How To Make Life Easier. To create a dynamic drop down list in Excel, you need to use this formula in Data Validation. Return array's size is the row number that returns from COUNTA('Create dynamic lists'!$B:$B)-1 Return array starts from 1 row below (1) and at the same column (0) =OFFSET('Create dynamic lists'!$B$2,1,0,COUNTA('Create dynamic lists'!$B:$B)-1) Argument But, If your list contains a title which you may not want to include, decrease the value from COUNTA by 1 to eliminate the title. Counting all nonblank cells in column B gives the size of our list. The COUNTA function can help us to find the size of the list. Because we have a vertical list through column B, we should make 4 th parameter, which refers to its Height, dynamic. We can make this output range dynamic by making its size dynamic. For example If the first argument is C5 and the other two arguments are -1 and 2 respectively, it refers to cell E4 which is 1 row above, 2 columns right.Īfter determining where the array starts, next two arguments, which are 4 th and 5 th, defines the size of the array. The first argument of the OFFSET function is a base reference followed by Rows and Cols arguments which defines the array's top left reference. The OFFSET function returns an array that starts from a specified reference and has specified height and width numbers. Using COUNTA function to return row count gives the entire formula the dynamic behavior we are looking for We are using the OFFSET function's ability to return arrays to generate dynamic lists. You can block changes in the first box (or, at least, force the user to clear the second selection before toggling the first dropdown again): changing the formula for the first drop down to IF(B2'',fruitlist,INDIRECT('fakerange')), as suggested for the simple formula. Type your name into Source box, with an equal sign =List.Click Data Validation under DATA tab in ribbon.Select the cell that will contains the drop down.Type ) to close the OFFSET function and finish the formula.Select the whole column that includes the list 'Create dynamic lists'!$B:$B.Continue with COUNTA( function to count filled cells.Type 0, to make the list start in the same column.Type 1, to make the list start at the next row, after the title.
Select title of your list 'Create dynamic lists'!$B$2,.Start formula with the =OFFSET( function.My formula of project Scope - NotesA1 only shows the first 7 lines, the last of which is cut off after 19 characters. Enter a name and clear Refer to formula box I have a load of text in a cell that I need to display in a text box on a different sheet.Click Define Name under FORMULAS tab in ribbon.=OFFSET(title of list, 1, 0, COUNTA(column that includes the list)-1) Steps This article shows you how to create a dynamic drop down list with the help of OFFSET and COUNTA functions. By filling in subsequent drop-down lists in response to what users select in other cells, you can make your spreadsheets far more responsive to users, and the data far more useful. Creating a dynamic Excel drop down list is very useful If you have a list that is updated frequently. Using Multiple Linked Drop-Down Lists in Excel As you can see, this is a very cool way to make your spreadsheets much more dynamic.
