As far as possible, I avoid using third party resources and I prefer natives. For a project, I need the native HTML5 date container but showing local vacations and blocked sundays.
Many third-party components/plugins allow them to spend the holidays, but do not use the native date-picker, but are customized. I prefer the native not to have to deal with the Browser and the device being used (desktop, Android or iOS).
I will use min="xxxx-xx-xx" and max="xxxx-xx-xx" to establish the range of days available to choose, but is it possible to block specific days within that range or do I have to use the resource of a third?
