Vue directive to compile custom directives

I wrote a wrapper directive that utilizes vue's Render function. Inside the render function all it does is:

render: function(createElement) {
    const compiled = Vue.compile(this.$props.template);
    return compiled.render.call(this, createElement);
}

I'm using like:

<Render v-for="item in itemsToRender" :key="item.id" />

This works for native html elements:

const itemsToRender = ['<p>test</p>', '<h1>HELLO</h1>'];

However if I pass in my own custom directive like 

<my-directive></my-directive>

Then vue will complain about unknown components. This is probably because I don't have the custom directive imported/required in the render directive's context. Is there a work around for this? The reason I need to have this wrapper directive do the compile is because libraries like vue.Draggable, rely on 'v-for' to reorder the list elements. However, I want to be able to have different components be draggable, which is why i'm passing just templates to compile into the v-for.

You can use the component tag. Check out: https://v2.vuejs.org/v2/guide/components.html#Dynamic-Components

I have made an example here: https://codepen.io/bergur/pen/jjwzEq

The flow is roughly this:

  1. I register the components within my app
  2. List them up in the listItemsToRender data property
  3. Use the <component> tag to render them

Here is the code

new Vue({
  name: 'main',
  el: '#main',  
  components: {
    CompA,
    CompB
  },
  data() {
    return {
      header: 'Multiple components',
      itemsToRender: [CompA, CompB]           
    }
  },  
  template: `
  <div>
     {{ header }}
     <component v-for="item in itemsToRender" :is="item" />
  </div>`
})
