scrolldown for samplemap menu

[staiff]

hello !
i learn and used the samplemap menu as in the SampleMapExample and saw that there is no scrolldown menu.
i have a lot of samples/samplemap and if i had again 2 or 3 samplemaps the menu will go out of screen.

what lust i add to the JSON script to add a scrolldown to this menu example ?

Thanks.
