Ability to only show field when certain type is selected

Hi,

Another major missing functionality is the ability to only show a custom field when a certain type is selected, especially at the dependant field level.

For example​​​​​​​:

If you have a “tracking link” field. You want this to be hidden only if you select a dependant set of fields - EG:​​​​​​​

Show “tracking link” if “Hardware” > “Delivery” is selected

Thanks
