Stack

Source@react-form-builder/components-material-ui

Introduction

The Stack component manages layout of immediate children along the vertical or horizontal axis with optional spacing and dividers. It is a one-dimensional layout component that simplifies the arrangement of elements in a linear flow, replacing the need for manual margin/padding calculations. The component follows Material Design layout principles with consistent spacing and responsive behavior.

The Stack component is based on Material UI Stack. It is included within the following NPM package: @react-form-builder/components-material-ui.

The Stack component can be styled and configured to fit specific design and functionality requirements by using various properties that are presented and described below.
