How to add multiple suffixes for an integer field type? Is there a way to add multiple suffixes for an integer field type? For example, I want to input a value, and I want to be able to specify whether this is in inches or centimeters with a drop down box.

Is there a way to do this using only the field module?
There are 3 options:


Install the Measured Value Field module.
In your custom module implement hook_form_alter and add your dropdown there with markups.
Create actual dropdown and work with just markup.
