Selectize field (not dropdown) max height

[reformed]

Is there a way to limit the max height of a Selectize field? The field itself, not the dropdown. The field in question needs to allow all options to be selected, so the option maxItems cannot be used. The maxOptions option can't be used either because that applies to the dropdown.

Is there a way to reduce the height of a field like this?

Example:

    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/selectize.js/0.13.3/css/selectize.min.css">
    <link href="https://cdnjs.cloudflare.com/ajax/libs/selectize.js/0.13.3/css/selectize.bootstrap3.min.css" rel="stylesheet" />

    <div id="container" style="max-width: 400px;">
      <form>
        <select id="selectize" name="selectize" class="form-control" multiple></select>
        <button type="submit" class="btn btn-success">Submit</button>
      </form>
    </div>

    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/selectize.js/0.13.3/js/standalone/selectize.min.js"></script>
    <script>
        (function($select) {
          for (let i = 100; i < 202; ++i) {
            $select.append('<option value="' + i + '" selected>Test ' + i + '</option>');
            $select.append('<option value="' + (2 * i) + '">Test ' + (2 * i) + '</option>');
          }

          $select.selectize();
        })($("#selectize"));
    </script>

If I am following the question you can use CSS to add a max height on the .selectize-input class.
An example is here: https://codepen.io/risadams/pen/WNXeJjK

This approach makes an "at a glance" view of what has already been selected extremely difficult. You can only see the last 2 rows or so of selected items, and scrolling does nothing. In order to view some of the earlier selections, you have to continuously press the left arrow key.

I added a div container around the select element with a max-height and overflow-y, then set the Selectize option dropdownParent to "body". This seems to solve both problems: https://codepen.io/reformed05/pen/PoOYeye

Wrapping the select field in a container with CSS max-height and overflow-y set to "auto", and then setting the Selectize option dropdownParent to "body" seems to solve the problem. Example: https://codepen.io/reformed05/pen/PoOYeye
