Hi @jletesson,
Could you please explain it to me again in more detail? If you want to display only the repeater fields in your form, you can use 'fields' => field_1234567890,
option in your acf_form (field_1234567890 is the key of your acf field). This page should give you more idea about it: http://www.advancedcustomfields.com/resources/acf_form/.
I hope this helps.
