How to open multiple pages in the same app? - aurelia

Question

I know that Aurelia is a framework for an SPA but I need to open multiple pages at the same time inside the browser.
I want to host each page (view/viewmodel) within a draggable div and have more than one open at the same time. They will be selected by the User from a menu.
I have looked at viewPorts but cannot see how they will help in this problem.
Is there another way to do this?

Yes, there is a way to do this.
You say pages, but basically they are components. Every component has a HTML (view) and JS (view-model) file. They can be included as custom-elements.
So if you want multiple possible components on one page, all you need to do is create one component that has a placeholder for those views.
Probably, you would want something looking like this:
running Gist example
<template>
<require from="./page1"></require>
<require from="./page2"></require>
<page1></page1>
<hr>
<page2></page2>
</template>
You can create loop for all elements you want to display, if you need multiple instances of the same page, and put a repeat.for on the elements:
HTML:
<template>
<require from="./page1"></require>
<require from="./page2"></require>
<page1 repeat.for="i of page1instances"></page1>
<hr>
<page2 repeat.for="i of page2instances"></page2>
</template>
JS:
export class App {
const page1Instances = 4;
}
Making them drag&droppable works like every other element, there are many solutions for that to be found. Just make the <page1> and <page2> draggable.
