Example 1

A mobile phone retailer wants its customers to select their preferred location for store pickup. With a nested picklist, itcan obtain the customer's country, state or province, and city through a single option. Here's how to nest these values:

 

Picklist label: Location

Picklist values:

Option 1 -> None (Default)

 Option 2 -> US :: Washington :: Seattle 

Option 3 -> US :: California :: Los Angeles

Option 4 -> US :: California :: San Francisco

Option 5 -> Canada :: Ontario :: Toronto

Option 6 -> Canada :: Ontario :: Toronto

The nested picklist field will look like this on the Ticket Add form.

Example 2

A company wants to know how its employees commute to the office so it can optimize its parking system. Here's how it can create a nested picklist field to obtain this data: 

Picklist label: Mode of commutation

Picklist values:

Option 1 - None (Default)

Option 2 - Car :: Personal

Option 3 - Car :: Pool   

Option 4 - Car :: Company  

Option 5 - Bike

Option 6 - Public Transport :: Bus   

Option 7 - Public Transport :: Metro

This is what the field will look like on the Record Creation form.

Note

1. The levels of a nested picklist are separated by double colons (::). For example: Category :: subcategory :: further subcategory. Let's call this the "actual format." 
   
2. A maximum of 500 nested picklist options can be added.
3. The picklist field will be auto-filled with a default value, which is generally the first option on the Creation form. However, you can set any option as the default during field creation/editing. Picklist values must be entered the same way they appear on the Create/Edit Field form while using criteria and search. In other words, they must be entered in the "actual format". For example, to create a custom view of tickets with customers located in Los Angeles:
