On the Custom fields tab of the unit properties, you can create fields that display additional information about the unit, for example, fuel type, year of manufacture, load capacity, etc. Moreover, here you can indicate any external links. Some of these fields can be marked as administrative (the checkbox before the field), i.e. they are visible only to users with the appropriate rights.
The required access:
Enter a field name and its value and click the Add button. To delete an incorrect field, click Remove.
The next time you open the unit properties, the entered fields will automatically be arranged in alphabetical order.
