How do you make multiple selects visually display many in table view?

  {
    label: 'Tags',
    name:  'webcolors.tags',
    type:  "select",
    multiple: true,
    height: '3em',
    separator: '|',
    default: '',
    options: [
      { label: "", value: "" },
      { label: "pastel", value: "pastel" },
      { label: "power", value: "power" },
      { label: "neutral", value: "neutral" },
      { label: "blue", value: "blue" },
      { label: "green", value: "green" },
      { label: "red", value: "red" },
    ],
  }

This works perfect in popup editor view. In table view when you click on the edit field it only displays a single item in the list. The other items are there but you have to scroll up/down making it awkward to select multiple (control-c).
