  import GridLayout from 'vue3-drr-grid-layout'
  import 'vue3-drr-grid-layout/dist/style.css'

  const app = createApp(App)

  app.use(GridLayout)

  app.mount('#app')

// swaps grid items standing next to each other when moving horizontally
horizontalShift: boolean = false

Responsive grid layout props

// To enable responsive mode, the responsive prop must be true.
responsive: boolean = false
// 6 display widths
// Window witch > lg component use layout prop
breakpoints: object = { lg: 1200, md: 996, sm: 768, xs: 480, xxs: 0 }

Intersection observer grid layout props

Documentation

useObserver: boolean = false
// Intersection observer config { ...propsConfig, ...defaultConfig }
intersectionObserverConfig: object = { root: null, rootMargin: '8px', threshold: 0.40 }

Grid layout emits

• @container-resized
  • When layout container was resized

    {
        i: number // grid item index

        height: number // grid item height
        width: number // grid item width
     }

• @resize
  • Grid item resize event

    i: number // grid item index
    h: number // grid item height from propss
