Dear Lavada,
For input any "target" options to link you should create <a> tag with "target" attribute, and set his "href" attribute as your link custom type field value.
For example:
<a target='_blank' href="[types field="url-field" raw="true"][/types]">Link Text</a>
Please let me know if you are satisfied with my answer and if I can help you with any other questions you might have.
Regards,
Victor
