//remove a property from the base question class and as result from all questions
Survey.Serializer.removeProperty("question", "visibleIf");

const options = { showLogicTab: true };            
                var creator = new SurveyCreator.SurveyCreator(options);
                creator.toolboxLocation = "right";
            
                
                    ReactDOM.render(
                    <React.StrictMode>
                        <SurveyCreator.SurveyCreatorComponent creator={creator} />
                    </React.StrictMode>,
                    document.getElementById("creatorElement")
                    );
                
creator.onShowingProperty.add(function(sender, options){
    if(options.obj.getType() == "survey") {
        options.canShow = options.property.name == "title";
    }
});
//It will re-create creator survey, select survey object in property grid again,
//and as result apply onShowingProperty event
//In real application you can set your JSON from database here or use creator.text property
creator.JSON = {};
