How can I make the nav menu collapse and expand with a smooth animation rather than the jerk? Please check www.mobilewebbestpractices.com/index.html on small resolution to see what I would like to have?
The reason it's slow is that the system can't draw the frames quickly enough to make it a smooth animation.
The solution I've found to this problem is to stop using animation altogether.
You might try code similar to the following...
$(function() {
$('.btn.btn-navbar').live('click', function() {
$('.nav-collapse').toggle();
});
});

How can we make smooth scroll from locomotive scroll and scroll triggered animations (with framer motion and react-intersection-observer) coexist ?
I've made a very basic codesandbox with smooth scroll enabled and a small animation scroll triggered and as you can see the animation is very "buggy" (to see it, you have to open the codesandbox browser in a new window, if not, the smooth scroll doesn't work - and the animations works fine) :
https://codesandbox.io/s/smooth-scroll-framer-motion-8z5u8s?file=/src/App.js
Maybe I implemented locomotive scroll in a bad way ? Maybe I did something wrong with the animation ? Maybe it's simply impossible ? You tell me :)

I added two Lottie animations to my wpf project and when both native animations and lottie animations are rendered at the same time, the native ones have slown down to almost a crawl.
Is there any way to pre-render the animations? Or any other suggestions?
The solution I figured out is to load the animations when I need them and dispose of them when I'm done. I am using them in button, so my solution for now is, when the button appears, to load it:
animation = new LottieAnimationView();
animation.SetAnimationAsync("Assets/Images/image.json");
animation.Scale = 1.5;
button.Content = animation;
And when the button leaves the view:
button.Content = "";
animation.Dispose();
I am not a fan of the solution, but at least the other animations that run at the other times aren't lagging anymore.
I am writing a Single Web App with material ui, that needs to be responsive, but I do not know which is the control where I must allocate the mains component, if it is a grid or a box.
The next image show the main components arrangement in md,lg,xl
The next image show the main components arrangement in sm,xs when width < 960
In the web I found many complex and very difficult to understand layouts, but not find a basic example. Some like "material ui responsive for dummies".
The mobile version, will have a breakpage between the Appbar and Sidenav, both will occupy the full height, and the Map in the second page will fill the screen.
I did it for you with MU Grids and media queries, if you have questions, ask. I am always ready to help. This is codesandbox link. Let me know if it help you.

Show my codesandbox answering your problem : https://codesandbox.io/s/amazing-sound-1nj87
It display your layout for md lg xl correctly. For xs and sm screens, sidenav & map take full height with a break page between sidenav and appBar
Thanks to both, it solved the main part o what i need.
Also need to implement a change of page.
I forget to mention that the map will be React-Leaflet,
so need to implement a flap button over the map for the mobile version.
The button is for scroll to up, because any finger movement in the map area only will affect the map content.
Do not will have effect in the scroll.
Another thing to implement is the break page concept:
The behaviour of the break page is like when you see a pdf in presentation mode and press
the keyboard button Repag - Avpag, it change all the content and never see the half top and the half down.

I'm currently developing a mobile web application with AngularJS, ngAnimate, Angular-Material and UI-Router. I'm following Google Material Design specifications for the UI/UX part.
I'd like to animate a state change 'the Angular way' and especially this 'Parent to child' animation
I've no idea on how to achieve this 'lift & expand' animation.
Thanks for your help !
You have to do it yourself, I guess.
Angular-material is not a magic wand that replicates the animation guidelines of Material Design. Material Design guidelines are simply guidelines, and are loose enough to be hacked — or strictly followed, in the case of Google's Android apps (in-house or not).
My feeling is the angular material team is already pushing like maniacs to bring this awesome tool to 1.0, and will take advantage of the new routing system in Angular 2 to provide some animations like the one you wish to attain out of the box.
But it's the bleeding edge of the bleeding edge, at least for the time being.
Good news seem to be that routes will have their own viewports and sibling viewports.
AngularJS somewhat starts to embrace Polymer's web components concept.
Scroll to "Show me the magic!" on this page, and check these demos. Polymer's ecosystem provides a lot of already-made components to build your app with. It's quite large, and makes you wonder why Polymer doesn't get the same momentum as AngularJS. But I digress...
Option 1
create a custom-made function that gets triggered on a list element being clicked/tapped, to place in your controller (or directive).
Once the user clicks/taps the list element, it triggers the function (console test).
The function should :
retrieve the id of the clicked/tapped item (pass it to the function)
animate : here you have several choices, but here's one : use a ui-router absolute named view (#view_name), and wrap it in a div container with overflow:hidden, that has inital dimensions corresponding to the dimensions of a list item.
Detect the x-y position of the list element that has been clicked (an example, assuming you use AngularJS with jQuery), and you pass it to the "item detail" route (see above), so the rectangle grows with origins corresponding exactly to where the UI is a the moment of the click/tap. The animation shown in the video seems pretty complex: the "item detail page" grows slower on the bottom and faster on the top, when the bottom item is clicked.
Why an absolute named view? Because it will allow, with z-indexing, for the list to stay underneath the "item detail" view, so when the user closes/leaves it, you can roll back your animation, and the rectangle will shrink back to exactly the dimensions and position of the list item. Finally, you transition the opacity:0 and leave the route.
Option 2
Here's a rough mockup of a technique stretching/scrolling an ion-item. It would require to detect the y position of the item, and use ionicScrollDelegate to scroll to it. Also, you would freeze the main scroll so the user get "stucked", until he closes the "detail view", which then releases the scroll.
$scope.toggleStretchedMode = function(itemID) {
$scope.stretched = $scope.stretched === false ? true: false;
if(!$scope.stretched){
$('ion-item').removeClass('stretched');
$ionicScrollDelegate.freezeAllScrolls(false);
}
else
{
$location.hash(itemID);
$ionicScrollDelegate.$getByHandle('mainScroll').anchorScroll(true);
$ionicScrollDelegate.freezeAllScrolls(true);
$('#'+itemID).addClass('stretched');
};
}
A very basic JSFiddle, which needs to be refined (clicked item should scroll to the middle of the screen, then expand).
Note that the JSFiddle only blocks the mousewheel scroll. If seems to block the first swipe, but then the ng-click releases it, so as it is it's far from perfect. You should not only block the list scrolling, but the up and down swipe events.
Also it initalizes badly, only works the second time. But the concept could be something like this.
I have a ng-grid that has scrollbars (default).
The ng-grid triggers the ngGridEventScroll event (api) when you are at the bottom of the grid.
So far so good but I want this behaviour when there are no scrollbars. The only way I could turn these scrollbars off is by using the ng-grid-flexible-height.js plugin but then the ngGridEventScroll event is ignored.
I there a way to get this event when you're at the bottom of the grid?
Are there other ways to throw your own custom event?
When using a custom event, the ideal situation would be to throw the event when you're at the last 'x' records (to preload data).
There is a jsfiddle here (with flexible height plugin enabled, to disable comment out: ,plugins: [new ngGridFlexibleHeightPlugin()])
Thanks for any input!
I checked the documentation and I dont think Ng Grid provides incremental loading. You ll need to write custom code for it.
You could use some jquery like as discussed here - Auto Load More Data On Page Scroll (jQuery/PHP)
$(window).scroll(function() { //detect page scroll
if ($(window).scrollTop() + $(window).height() == $(document).height()) //user scrolled to bottom of the page?
{ // do your stuff here; }
});
Or better use a jquery plugin like this one - jQuery Waypoints | Example
