@henryavila This isn't for a general Vue.js application! This snippet expects to be in an environment provided by Laravel Nova.
If you're interested in a general use modal component for Vue.js, I strongly suggest you check out the examples section in the docs: https://vuejs.org/v2/examples/modal.html

Thanks for quick response @blackfyre. In fact I'm using Laravel Nova. I'm new in VueJS and automatically the way Laravel Nova use it. I'm a backend (php) developer starting with the frontend with Laravel Nova.

If you could give some direction, I will be so gald.
For example. I create a Card in Laravel Nova. And whant this card to display a Modal. In this case, the Tool.vue in your gist represent my Card vue file? Then where do I put the GeneralModal.vue (from your gist) file?

@henryavila
Thanks for the background, this puts things into perspective 😄
Haven't developed a Card before, but the match between the Card & Tool vue files seems reasonable.
As for placing the GeneralModal.vue file is totally up to you! At some point, you'll have to reference it in your card vue file.

Hello everyone, today i face one problem that I can't use improted component inside this <modal> tag, maybe I do something wrong, I wanted to use vuedraggable to make some functionality inside my project, but i couldn't because <draggable> tag is not initialize like draggable component. After I tried to make my own component just with test content like "Hello world" and import that component and use it inside <modal> tag, the same result. Laravel Nova

If i need two modals in my tool.vue, i need to make two but this does not work I mean if i have two components GeneralModal and TableModal both using difference betwen componentes is only the contenu in the Nova modal's slot, how could I have two modals ?

thanks for this mehn

Thank you for your sharing; I fixed it for Nova 4 like this:
Similar to your implementation but changed to match laravel/nova/resources/js/components/Modals/DeleteResourceModal.vue

GeneralModal.vue

@bmoex thanks for the snippet. any idea how to trigger the auto close on click away functionality? I can see that Nova 4 native modals have it

You really can't do that without modifying the nova code as it usually involves a click listener on the backdrop.
