Getting Started

Installation

npm

# install with npm    
npm install vue-grid-layout --save

GridLayout

• layout

Events

Move and resize event listeners can be added to each grid-item, so that the parent Vue can be notified when a grid element is being moved or resized. Moved and resized event listeners can be added, if the only notification needed is when an item is finished moving or resizing.
