This may be a dumb question but in videos I watched of real life cockpit in planes like 777 no one is controlling yoke while taxing or I am really missing them. How can that be possible or am I missing?

They use a cockpit Tiller just to the side of the pilots knee, like a D shaped handle, it controls the nose wheel steering. Google it and you can see some pictures.  If you have the PMDG NGX, you can can see it and use it in the cockpit.  

No need to touch the yoke while taxiing, the nose wheel is controlled with a tiller handle to the left on the captains side. During rollup / rollout the rudder pedals are used to control the nose wheel, the movement excersized on the nose wheel steering is much "finer" when using the rudder pedals than the tiller handle, thus the tiller is only used when taxiing at low speed.

The tiller is a little crank sort of object that you turn one way the nose wheel turns that way.

Is it possible to assign it to joystick?

If so,then why not use the rudder? (If you have a rudder ofcourse )

In certain aircraft, yes.  In the Majestic Q400 you can.  Maybe the only one?  I'm not sure of others now to be honest.

I have the joystick as my tiller for all aircraft that have one, the twisting axis.

I just assigned the majestic tiller to the rudder pedals so I can keep my hands free for the taxi. The real one has a push to talk button on the tiller, so that the skipper can do radio calls with one hand on the tiller and the other on the throttles. Only found out that tidbit last week!
