Vue Scheduler Drag and Drop

Drag and drop

Move and resize events with the pointer — snapped to a configurable step, previewed live, cancellable with Escape.

On this page

Drag an event to move it; drag its top or bottom edge to resize. Both operations snap to the snap step (default 15 minutes), render a live preview, and can be abandoned with Escape before release.

vue
<script setup lang="ts">
import { CScheduler, type EventChangePayload } from '@coreui/vue-scheduler'
import { ref } from 'vue'

const pad = (n: number) => String(n).padStart(2, '0')
const day = (offset: number) => {
  const date = new Date()
  date.setDate(date.getDate() - ((date.getDay() + 6) % 7) + offset)
  return `${date.getFullYear()}-${pad(date.getMonth() + 1)}-${pad(date.getDate())}`
}

const events = [
  { id: 'kickoff', title: 'Kickoff', start: `${day(0)}T09:00`, end: `${day(0)}T10:00` },
  { id: 'review', title: 'Review', start: `${day(2)}T13:00`, end: `${day(2)}T14:30`, color: '#2eb85c' }
]

const log = ref('')

const onEventChange = (change: EventChangePayload) => {
  log.value = `${change.action}: ${change.event.title} → ${change.event.start}`
}
</script>

<template>
  <CScheduler
    :day-start-hour="8"
    :day-end-hour="18"
    :snap="30"

Touch

On touch devices the grids pan natively — a drag starts from a long press (~300 ms): hold an event until it engages, then move; page scrolling is suppressed for the rest of the gesture and Escape still cancels. A quick tap keeps its click semantics (selection + edit dialog), and moving your finger right away simply scrolls.

The eventChange payload

Every committed operation emits eventChange:

PropertyDescription
action'create', 'move', 'resize', 'update' or 'delete'.
eventThe event with its updated ISO dates.
occurrenceThe affected occurrence (key, start, end), or null for create.
revertCall to restore the previous state — e.g. when your API rejects the change.
scopeFor recurring events: 'occurrence', 'future' or 'all'.

Moving or resizing a single occurrence of a recurring event detaches it by default: the series gains an exception date and the change materializes as a standalone event. See Recurrence for the other scopes.
