You need to add a name attribute   Since this is a multiple select  at the HTTP level  the client just sends multiple name value pairs with the same name  you can observe this yourself if you use a form with method  GET   someurl something 1 amp something 2 amp something 3   In the case of PHP  Ruby  and some other library frameworks out there  you would need to add square braces      at the end of the name  The frameworks will parse that string and wil present it in some easy to use format  like an array    Apart from manually parsing the request there s no language framework library-agnostic way of accessing multiple values  because they all have different APIs  For PHP you can use    lt select name  something    id  inscompSelected  multiple  multiple  class  lstSelected  gt
