How do you set #items in a multiple select list?

Description of problem:

I have a multiple select list. It defaults to display 4 items before scrolling. How do I change it to display a custom value?

The select list size is not controlled by Datatables. You will need to set the appropriate select attribute to do what you want. Here is one example:

I use size in non-datatables forms and it works perfectly. I tried this in DT but it has no effect:

  {
    label: 'Page assignment:',
    name:  'url',
    type:  "select",
    size: "10",
    multiple: true,
    separator: ":",
    ...

}

"size" is not a valid property for a DataTables select.
Apply it to HTML as Kevin showed.

Didn't realize you were using Editor. See if using attr works, like this:

{
  label: 'Page assignment:',
  name:  'url',
  type:  "select",
  attr: {
    size: "10",
  },
  multiple: true,
  separator: ":",
  ...
