How To Create Dropdown Checkbox List On Each Row

I would like to know if there's a way to create a checkbox list in a cell that influences other cells:

For example, I would have column A as "Materials Accepted", and each cell would have a dropdown list with the options "Wood", "Drywall", and "Metal", in checkbox format. Then to the right of that, I would have each of the Materials as actual columns so that column B is "Wood", column C is "Drywall", and column D is "Metal".

The way I would want it to work from there is that whatever options I select from the dropdown, it would then put a TRUE flag in that column. So if I select "Wood" and "Metal" on the dropdown checkbox list, columns B and D would both read TRUE on that particular row.

Here is a screenshot of a mockup I did in paint - [URL]

Basically on each row, I would select a number of Materials, and the following columns for those Materials would populate TRUE for the ones that I selected on that row. This was just an example, but I would scale this up to around 30 Materials for hundreds of rows/entries.
