const form = ref({
  name: '',
  category: '',
  date: '',
})

const categoryOptions = [
  { value: 'A', label: 'Category A' },
  { value: 'B', label: 'Category B' },
]

const submit = () => {
  console.log('Form submitted:', form.value)
}
</script>

<template>
  <form @submit.prevent="submit">
    <KbxInput
      v-model="form.name"

const dialogOpen = ref(false)
const selectedRow = ref(null)
</script>

<template>
  <div>
    <KbxDataGrid
      :columns="columns"
      :rows="items"
      @row-click="(row) => { selectedRow = row; dialogOpen = true }"
    />
