gistfile1.js

let options;

export const CustomSelect = {
    template: `
<select @change="$emit('input', $event.target.value)">
    <option v-for="e in options" :key="e.key" :value="e.value" :selected="e.value === value">{{ e.label }}</option>
</select>`,
    props: {
        value: String
    },
    data() {
        return { options };
    }
};
