Render a list of multiple values in multiple lines

[gilles]

I would like to render a list of multiple values in multiple lines, and not into a comma separated list (as the actual MultiValueConverter does ).
As the text generayed by the MultiValueConverter is escaped for javascript, I can't just replace the commas by '<BR/>'s .
Any idea? (I use the 2.9) Thanks in advance.

Are you looking to generate a multi-value select dropdown?

I don't want another multi-value 'select', the one used by Alflresco seems to work well, but just a multi-value renderer where each value is shown on one row, and not in a comma-separated (but continuous) text as it is now ( 2.9).
