How To Create Multiple Checkbox Lists In Each Cell

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.

Just wondering if something like this is possible, as I wanted to apply this concept to a much larger scale (About 29 columns for 29 Materials, scrolling left and right is really time consuming). So far I've only seen guides on how to create a SINGLE checkbox on a row, and none with multiple checkboxes that would function in this manner.
