[Feature][QCheckbox] add option to hide checkbox

[gimler]

I need a form element where the user can select 1 or more images. First i try https://quasar.dev/vue-components/button-toggle it works but not for multiple.

Then QOptionGroup and use the label slot to render image for each option. It works for radio and checkbox single and multiple values.

Now i need to hide the checkbox my workaround is with css

.image-choice .q-checkbox__inner {
  display:none;
}

It would be great if the QOptionGroup has a option for hide checkbox.

Also a label and label-toggle class whould be great. my workaround

<template v-slot:label="opt">
    <div class="row items-center q-pa-sm" :class="{'bg-yellow-2': !model.includes(opt.value), 'bg-amber-5': model.includes(opt.value)}">
        <img :src="opt.img" :title="opt.title" height="50">
    </div>
</template>
