In here, and all it's closely related links, I cant find anything that tells me how to set a list of the optional arguments.
All I want is something like this
Options[myfunc] = { a->0 };
myfunc[x_,OptionsPattern[]]:=Block[....]
Say, by default, a is 0. How do I setup something like when I use
myfunc[100, a->
would trigger a drop down list of values, {0,10,100,True,False} for me to choose?
I would think it can be easily found in the link above, or some of the links on its page. But it's just nowhere to be found!
