Thank you for you answer. Is there any (hacky) way to handle this else?
E.g. from the vue comp, I could post the slot to the backend (with the user's IP address?) and if the blade form will be submitted, I submit the IP address as well and try to match them up?
I am comping from a Laravel + Blade Stack and my old projects are using this. Nowadays I am using Inertia with vue and no blade. From a newer project I have a reactive meeting planning component that I want to re-use in an old project. The implementation was very straight forward and it's working.
All the component does, is selecting a time slot in a form, but in a fancy reactive vueish way. That's way I want to use it. Think of it as a datepicker.
The only downside I am facing now, is that I can't use the selected value in the parental blade form.
