Table 1. Custom field types

Types	Description
Drop-down list	This field enables you to create a list of options for users to select. Each option is a combination of a title and a tag. The title is displayed to users and the tag is used as a ticket property that you can use in business rules. You can create up to 2,000 values in custom drop-down menu. You can select which field appears as the default option in the drop-down list using or choose to not display a field value as a default. Note: When you configure a default option in a drop-down list, this only applies to new tickets that are created by agents through the Support interface or created by users wherever the ticket form is displayed. If you change an existing ticket form to one that contains a drop-down list with a default option, the default option is not displayed and is shown as blank. You can organize drop-down list options into categories (see Organizing drop-down and multi-select list options).
Multi-select	This field enables users to choose multiple options from a predetermined list. You can create up to 2,000 values in custom multi-select list. You can organize options into categories (see Organizing drop-down and multi-select list options).
Text	This is a simple single line text input.
Multi-line text	This is a multiple line text input.
Numeric	This is for simple numeric input (no decimals). Values entered in custom numeric fields for organizations can't exceed 12 digits. There are no restrictions on the length of values in custom numeric fields for tickets or users.
Decimal	This is for numbers that contain decimals.
Checkbox	This is used to capture a Yes/No value. Enter a tag to be added to the ticket when the checkbox is selected. Use the tag to filter your views, triggers and automations.
Date	Custom date fields allow your users to select a date from a date picker. Users can choose the current date or any date in the past or future. Community tip! Colin shows how to use custom date fields to set reminders for on-hold tickets. Check it out in our community forums.
Credit card number	This field allows users to enter a credit card number in a secure, PCI compliant manner. Only the last four digits are visible to agents and stored by Zendesk.
Regex	You can enter a Ruby regular expression to create an input mask to validate proper entry of numbers in fixed patterns (telephone numbers, zip codes, social security numbers, etc). Here's a regular expression for a U.S. social security number. This expression requires three sets of numbers (0-9 only) in a pattern of 3-2-4 and each separated by a dash \b[0-9]{3}-[0-9]{2}-[0-9]{4}\b Other common regular expressions include: URL validation: ^(http|https):\/\/[a-z0-9]+([-.]{1}[a-z0-9]+)*\.[a-z]{2,5}(([0-9]{1,5})?\/.*)?$ Five-digit zip codes: \b[0-9]{5}(?:-[0-9]{4})?\b yyyy-mm-dd date: \b([0-9]{4})-(1[0-2]|0?[1-9])-(3[0-1]|[1-2][0-9]|0?[1-9])\b For more information about Ruby regular expressions, see Rubular.
