# Not allow deselect option value

When this feature is activated:

* Customers can switch between option values
* Customers **cannot deselect** the currently selected value
* One option value will always remain selected

This helps prevent accidental unselection and ensures required input is always provided.

## I. **Available options**

This feature works only with **single-selection** option types:

* Color swatch
* Image swatch
* Radio button
* Button

> ⚠️ This feature does **not** apply to multi-select options (e.g. checkboxes).
