For those of you with older versions of Excel i also have an update to the method in this video:
Easiest Multi Level Excel Drop Down List
A more robust solution here

One-Off dependent drop down lists in data validation are relatively straightforward: here's a technique using XLOOKUP. https://youtu.be/5Z2OOriFxig
!!BUT!! if you want row after row of dependent lists it needs a different approach.
I've seen a lot of solutions out there that attempt to solve this, I've even done a crazy one a few months back, but this is by far the easiest technique I've come across.
⚠️ To prevent any value being typed in the dependent validation boxes you MUST UNTICK "Ignore Blanks". This in my view is a bug and will hopefully be fixed one day.
00:00 Intro
01:06 The Setup
01:50 Formula 1
=UNIQUE(tblOptions[List1])
02:53 Formula 2
=TOROW(
UNIQUE(
FILTER( tblOptions[List2], tblOptions[List1]=G6, "Empty List")))
04:50 Formula 3
=XLOOKUP(AB5, Level1Choice, Level2Result )#excel
06:14 Apply formulas to Data Validation
08:04 The Second Level List
10:36 Conditional Formatting
=COUNTIFS( XLOOKUP( I7, Level2Choice, Level3Result )#, J7)=0
