# Nest Content Within Choice Options (React)

Survey authors can insert questions and panels inside individual choice options in Checkboxes and Radio Button Group questions. These nested elements appear dynamically when respondents select the corresponding option. To add a nested question or panel, click the button on the right side of a choice option on the design surface.

To enable this feature in Survey Creator, set the [`maxChoiceContentNestingLevel`](/survey-creator/documentation/api-reference/icreatoroptions#maxChoiceContentNestingLevel) property to an integer value. This property defines how many levels of nesting are allowed:

- 0 - Disables nesting (default).
- 1 - Allows first-level choice options to contain survey elements.
- 2 - Allows first- and second-level choice options to contain survey elements, and so on.

In this demo, the `maxChoiceContentNestingLevel` property is set to 2.
