INPUT question

[Giancarlo]

Hello,
I was playing with the input command and tested some checkboxes.

As ibdicated in the help menu it is possible to display checkboxes like this where you can flag both item:

LOCAL A, B;
INPUT ({{A, 1}, {B, 1}}, "title", {"black", "white"});

But it is possible to avoid that both checkboxes are flagged like here:

LOCAL A, B;
INPUT ({{A, 2}, {B, 2}}, "title", {"black", "white"});

But it is also possible to combined together more checkboxes with that option that gives the possibility to check one of the three colors and one of the two shapes:

LOCAL A, B, C, D, E;
INPUT ({{A, 3}, {B, 3}, {C, 3}, {D, 2}, {E, 2}}, "title", {"black", "grey", "white", "square", "circle"});

Very nice feature,

Giancarlo
