You can create your Contact Forms on Makerble.
The Contact Forms serve as the means to register new clients, beneficiaries, service users, stakeholders, partners, and any other category of 'contact'.
Note: when you want to add a List field (e.g. Gender) to a Contact Form, create the List field and then you can add it to a new or existing contact form.
Steps
Click on the My Apps on the top menu.
Scroll across to the right and click on Contact Forms.
You now arrive on the Manage Contact Forms page.
Click on the New Contact Form button.
You are now on the Create Contact Form page.
Select the Contact Type by clicking on the radio buttons. Contact Type tells you whose details are recorded using this form.
The Contact Type can be A Person, An Object, An Organization, or An Animal.
Choose the role from the drop-down list. By default, there is a role called Participant which you use.
You can also create a new role by selecting Create a New Role from the drop-down list.
When you select Create a New Role, a pop-up appears, asking you to enter the Role's name.
Once you have entered the name of the Role, click on Save. A new role is created which you can now use to create the contact form.
Next, give your Contact Form a name.
The right section called Your Contact Form displays the fields that are already in your Contact Form.
The left section called Your Library of fields can be used to add existing fields to your Contact Form and/or create new fields to add to the Contact Form.

Every Contact Form has a set of default fields which are added automatically. Those that you can remove have a
