FlexWrap

API Reference: UI.FlexLayout.FlexWrap

This property specifies whether children of FlexLayout are forced into a single row or can be wrapped onto other rows. It works like FlexWrap on CSS. Please refer to the following guide for more information: https://developer.mozilla.org/en-US/docs/Web/CSS/flex-wrap

Defaults to: UI.FlexLayout.FlexWrap.NO_WRAP

TypeScript code blocks include examples of how to implement, override and components within the theme. You can create page with the UI Editor to make your page compatible with theming and then you can implement themable components programmatically. Once the page is created with the UI Editor, it generates a class under scripts/generated/pages. You can then extend that class with the following TypeScript classes.
