I have built a user-defined component (async-select) on top of another component (vue mutliselect) like this:
https://jsfiddle.net/2x7n4rL6/4/
Since the original vue-multiselect component offers a couple of slots, I don't want to loose the chance to use them. So my goal is to make these slots available from inside my custom component. In other words, I want to something like this:
https://jsfiddle.net/2x7n4rL6/3/
But that code oes not work. However, if I add the slot to the child component itself, it works just fine (which you can see from the fact that options become red-colored).

After surfing the web, I have come across this article, but it does not seem to work Is there any way in VueJS to accomplish this ?
Slots can be confusing!
First, you need a template element to define the slot content:
<async-select :value="value" :options="options">
<template v-slot:option-tmpl="{ props }">
<div class="ui grid">
<div style="color: red">{{ props.option.name }}</div>
</div>
</template>
</async-select>
Then, in the parent component, you need a slot element. That slot element itself can be inside of another template element, so its contents can be put in a slot of its own parent.
<multiselect
label="name"
ref="multiselect"
v-model="localValue"
placeholder="My component"
:options="options"
:multiple="false"
:taggable="false">
<template slot="option" slot-scope="props">
<slot name="option-tmpl" :props="props"></slot>
</template>
</multiselect>
