Yes, of course (and a new form typically involves a new window).
If want to make it look more like a pop-up then show the form/
window without window decorations, i.e. call fl_show_form() with
the 'border' argument set to 'FL_NOBORDER'.

If you want the slider in the main window you can also create
all the slidwers, but make them invisible at the start (using
fl_hide_object()) and, when the user selects an item, unhide
the corresponding slider (with fl_show_object()).

                           Best regards, Jens
