Selectmenu: custom separator in multiselect
The separator displaying the selected options in a multiselect selectmenu is a comma.
 
 
 
 
 This looks strange when options are sentenses with capitals.
 Example:

 Is it possible to change the separator from comma (,) to semicolon (;)?
 Now I have to modify the JQM source, but I prefer not to.
 
 Thanks!
