# Multi-Select Resource and Screen Field Considerations for Flows

Checkbox Group, Multi-Select Picklist, and Choice Lookup screen components let flow users select multiple choices. Before you start using these screen components, understand how they work in flows—both when you design the flow and when your users run it.

## Configuring a Checkbox Group, Multi-Select Picklist, or Choice Lookup Screen Component

- These screen components support only one default value. You can’t individually select multiple default values. However, you can manually add a value in the default value field and separate each value with a semicolon.
- You can configure a record choice set resource to assign field values from a user-selected record to variables in the flow. When a Checkbox Group, Multi-Select Picklist, or Choice Lookup screen component uses a record choice set, only values from the last record that the user selects are stored in the flow variables. If multiple Checkbox Group, Multi-Select Picklist, or Choice Lookup components on one screen use the same record choice set, the variable assignments come from the last record selected from all of those components.

## Using Values from a Checkbox Group, Multi-Select Picklist, or Choice Lookup Screen Component

- At run time, the value of a Checkbox Group, Multi-Select Picklist, or Choice Lookup screen component is a concatenation of the user-selected choice values, separated by semicolons. If a selected choice’s value includes semicolons, the semicolons are removed.
- If you reference a Checkbox Group, Multi-Select Picklist, or Choice Lookup screen component in a flow condition:
    - Make sure that each choice in the screen component has a choice value configured.
    - Don’t use the same choice in multiple Checkbox Group, Multi-Select Picklist, or Choice Lookup screen components on the same screen.
- If a Checkbox Group, Multi-Select Picklist, or Choice Lookup has at least one default value, at run time the choices are preselected if the choice’s value matches the default value.

Choice resources can appear as radio buttons, checkboxes, or picklist fields. There are several options for choice resources that you can use, depending on your business need. We recommend using a choice resource only when you can’t use a record choice set or a picklist choice set.")
