Nativescript - how to get layout to open on a tap

I've got a StackLayout where one of the entries is a GridLayout of a fixed size. Normally this GridLayout is not visible.

On tapping a button, I'd like the GridLayout be made visible - but I'd like to animate it open - - like a menu open.

Any ideas?

Actually toggling visibility is not too bad - it seems to animate the open - any way to control the speed?

The close operation is maybe too fast for what I'm trying to achieve.

You could animate the opacity of your grid. so when you click on it you would 

// View is your gridView, this would hide it completely
view.opacity = 0;

// when you want to show it.
// fade in view.
view.animate({
        opacity: 1,
        duration: 250 
        }).then(() => {
            //Set the visibility to collapsed after the animation is complete 
            //I believe you will want to do this so that the surrounding views adjust accordingly. 
            view.visibility='collapse';
        }, (err) => {});

// when you want to hide it.
// fade out.
view.animate({
        opacity: 0,
        duration: 250 
        }).then(() => {
           view.visibility='visible';
        }, (err) => {});

You also may want to look into translate for you animations so you can move view down, left, up, right any way you want.
