Effortlessly disable and remove values from checkboxes using Vue

I am working with a group of checkboxes, each with its own model. These checkboxes need to be enabled or disabled based on the state of a master checkbox. Enabling and disabling them is simple, as I just need to include :disabled="!MasterCheckbox" in each checkbox.

However, if I fill out some of these checkboxes and then decide to disable them, I want their values to revert back to false. My current solution involves using a v-on:change event on the master checkbox, where I manually set the values of each checkbox model to false by looping through a dictionary. While this method works, I'm curious if there is a more elegant or efficient way to achieve the same outcome. Perhaps there's a directive or prop that I could utilize instead. Any suggestions would be greatly appreciated.

Instead of relying solely on v-on:change, another approach is to utilize the watch property in Vue.js:

watch: {
    masterCheckbox: function(val, oldVal) {
        if (!val) {
            this.otherCheckbox= val;
            this.andOtherCheckBox = val;
        }
    }
}

This method can make your code a bit more concise as you eliminate the need for v-on:change on the master checkbox and potentially create a cleaner methods section.
