To recap, here's what you need to do for the simple version in the Simple Version tab:
1) Create a normal drop-down in Column A from the first column in the simpleData tab.
2) Create a transposed filter function in the simpleDropdown helper tab that will return the data from Column B in the simpleData tab for each row in Column A (starting in A2, then hover over the blue box and click and drag down to copy the formula down).
3) Create the hacked drop-down in Column B from the first row in the simpleDropdown helper tab for the 2nd row in Column B on the Simple Version tab.
4) Update the data validation to delete the "$"s so the row reference is not locked.
5) Select B2, then click and drag on the blue box on the bottom right to copy the data validation down.
