[Improvements] Add disable action

[Tropicalista]

At the moment the only action supported are hide and show. A nice addition would be a disable action.

This can be useful to disable certain field until a correct value is entered. And also the most used use case is to disable the button, for example if the privacy policy is not accepted.

I have digged a bit trough the code, but seems not a simple implementations at the moment. It would require some code refactoring.

Feature is added, you can now simply pass the enable/disable action in the rules.
For example:

// Parent Field
<input type="checkbox" name="disable_parent" id="disable_parent" value="yes"> <label for="disable_parent">


// Child field
<button type="submit" name="disable_this" class="btn btn-primary">Submit</button>


// Rule
{
    "field": "disable_this",
        "action": "disable",
        "rules": {
            "name": "disable_parent",
            "operator": "isnot",
            "value": "yes"
    }
}
