Go to Fields from Settings.
From here, you can add a new custom field, update the existing custom fields and archive/unarchive your custom/system fields.
While adding/updating fields to your website, Raklet gives you some options for data types such as text, number, float, date, and boolean.
These fields determine the way we save your data to our database. Inputs are rendered according to these data types. This affects the way you filter to find the information you want.
Here are the different filtering designs for different data types:
Date Field Results
Text Field Results
Option List Results
You can decide which information you want to ask for from your members. For example, if you want to add a field named "Years in Company", you should change the data type to numbers, and they will provide you with numbers for that question.
The only thing for you to decide is what to add as a field and which data type you need.
