The easiest method is simply typing your options with each one on a new line in the textarea of the tag generator form, e.g.:
Apples Bananas Dragon fruit
For a select controller field, the tag generator will display them like this:
[select_controller my_controller id:my-controller "Apples" "Bananas" "Dragon fruit"]And on the frontend, you’ll see the options for a select field’s HTML be outputted like this:
<select id="my-controller" ...>
<option value="Apples">Apples</option>
<option value="Bananas">Bananas</option>
<option value="Dragon fruit">Dragon fruit</option>
</select>
