MODULE OPTIONS
Some aspects of the 
Custom Field module can be customized by opening the module, clicking the Tools menu, and then selecting Module Options.
Module Options General tab
- Only show the required custom fields in the wizards
- With this option checked, only required custom fields will be shown in wizards. For example, when creating a new part, only the part custom fields that are marked as Required in the Custom Field module will be displayed, instead of all of the part custom fields.
