dependent dropdown size depends on selection

I've found multiple sources listing a myriad of ways to create a dependent dropdown list that either uses data validation and other options.

Is it possible to vary the total number of dropdown lists based on what is needed?

Say I have 3 items in a main list. The first and second have 3 levels of selections that could be selected from a dropdown list, but the third has a fourth.

How can I tailor the sheet to show the correct number of lists? I.e. the first two would only show 3 dropdowns, the third would show 4?

Or is it possible?

TIA.

*also, this is very new in the creating phase, although I can make a dummy sheet showing what I'm saying if it isn't clear...

Thanks, Cytop. See above.

Only one set goes through 4 levels, the others would not have information at that point. Maybe I leave it as is, and create a cell that returns which section is used last, and pulls the information from there... Not sure.

Thanks all.
