how can I disable an array of checkbox after checking a number of checkboxes from that array ? Is there a way to do this in vuejs or I will need a watcher for that? In fact I tried to watch the 'ord.sauce' but I couldnt make it work
this is the component
Vue.component('sauce-view', {
props: ["sauce", "ord", "name"],
template: '
<div class="">
<input type="checkbox" :name="name" :value="sauce.id" v-model="ord.sauce">
{{sauce.name}}
<label >
<img :src="sauce.link" >
</label>
</div>',
});
This is the HTML
<table>
<tr v-for="o in order" >
{{o.sauce}}
<td v-for="sauce in les_sauces" >
<sauce-view :sauce="sauce" :ord="o" :name="o.produit+o.num">
</sauce-view>
</td>
</tr></table>

I have created a simple fiddle that should illustrate the logic behind it: https://jsfiddle.net/UDany/r9q4x85d/
This would be the markup:
<div id="demo">
<template v-for="(item, index) in itemlist">
<label><input type="checkbox" :value="index" name="condiment" v-model="selectedItems" :disabled="selectedItems.length >= max && selectedItems.indexOf(index) == -1" /> {{item}}</label>
</template>
<div>{{selectedItems.join(', ')}}</div>
</div>
And your JS would look like this:
var demo = new Vue({
el: '#demo',
data: {
selectedItems: [],
itemlist: [
"Mayo",
"Ketchup",
"Mustard",
"Honey"
],
max: 2
}
})
Since you're not using the input directly into the main code you'll need to proxy the properties through/from it (possibly wiring events for "select" and "unselect" and having a property for "disabled")

I've answered a question very similar to this here:
Vue.js limit selected checkboxes to 5
In your situation it's a little more involved since you're handling the value in a component. It's hard to tell your exact needs so I'd clear up your question a little more.
