Setting the height of a multi select list

Setting the height of a multi select list

Is it possible to set the height of a multi-select, lookup field on a form? I tried the instructions here ( https://www.zoho.com/creator/help/fields/setting-field-width-and-height.html) to no avail. The height setting is missing.

Here's a screenshot of the form field in question:



Here's a screenshot of the field properties. Note that I have tried changing "field size" to be other values, including custom. It just change the width.


Any help is greatly appreciated.
