How set not-visible an item than not have the "visible" property?

Question

I have a button and a grid below. Inside the grid I have some elements (input, checkbox, label, ...) How can I set not visible all the elements inside the grid together together at once?

<Grid xmlns="sap.ui.layout" id="idGrid">
            <content>

                <Label xmlns="sap.m"
                    id="idLabel"
                    design="Standard"
                    text="the label">
                </Label>

                <Input xmlns="sap.m"
                    id="idInput"
                    value="the input">
                </Input> 

            </content> 
</Grid>

Answer 1

put the Grid content into a VerticalLayout.

sap.ui.controller("test.controller", {

   handleHide: function(oEvent) {
        var bt = oEvent.getSource();
        var vl = this.getView().byId("vlContent");
        if (vl.getVisible()) {
            vl.setVisible(false);
            bt.setText("Show");
        } else {
            vl.setVisible(true);
            bt.setText("Hide");
        }
    }
});

var oView = sap.ui.xmlview({
    viewContent: jQuery("#view1").html()
});
oView.placeAt("content");
