Hello @marcelohcortez,

Currently, traveler form field appear for all the travelers you set in the trip page but one thing is, except for the lead traveler, it is not necessary to fill up the form for other traveler.

But in coming updates we will definitely add the option to manage the setting.

Also, as a work around please add below given CSS so that it will remove the form for other traveler.

For this go to Admin Panel > Appearance > Customize > Additional CSS.

.checkout-accordion .panel-default {
	display:none;
}
.checkout-accordion .panel-default:first-child{
	display:block;
}

Hope this helps.

If you have any issues further then please let us know.

Thank you.

Regards!!
