I needed this feature while developing a plugin so I think that should be useful to share this with the community.
The main change is that an array can be used in
$vars['value']
to allow to select more of one value in dropdown box.To detect the values
in_array
function is used.With this change you can use code like this to output a multiple selection dropdown box:
Notes:
[]
so the form sends an array of values instead of only one.'multiple' => true
so format_attributes translates it inmultiple="multiple"
attribute in select form element.I'm waiting your comments about this feature ;)
