自定义选项渲染

经过了很久的思考，我决定放弃支持 Slot API。当然，还是提供自定义渲染选项的方式。

<n-select
  v-model="value"
  :options="options"
/>

import mdMusicalNote from 'naive-ui/lib/icons/md-musical-note'

function render (h, option, selected) {
  return [
    h('n-config-consumer', {
      props: {
        abstract: true
      },
      scopedSlots: {
        default ({ styleScheme }) {
          return h('n-icon', {
            style: {
              fill: selected ? styleScheme.primaryColor : styleScheme.tertiaryTextColor,
              verticalAlign: 'middle',
              marginRight: '4px',
            }
          }, [h(mdMusicalNote)])
        }
      }
    }),
    option.label
  ]
}

export default {
  data () {
    return {
