D flip-flop using basic gates + Clear

Question

I'm using Logisim to make basic circuits and they have in-built things such as Counter and D Flip-Flop. The D Flip-Flop looks like this:

It however doesn't show how it's made up of the basic gates (NAND, NOT, etc). I'm wanting to know how to create a D Flip-flop that can clear if Clear is equal to 1. I've tried searching it up but only get more complicated approaches to what I'm after.

Wikipedia has a pretty good section on gated D latches and D flipflops. (For the difference, read the article.) It should be trivial to add a clear input to either of these. — tcrosley, Apr 28 '16 at 06:19

Although there exists such device (CMOS 4013), you could look up into the 4013 datasheet on page 2 and see how they did it. Also that weird TG block if you don't know what that is, it is a Transmission Gate. https://en.wikipedia.org/wiki/Transmission_gate
