Card tile grid like google plus

How to create card tile scrolling grid like google plus, with three columns? I am using Material UI, but I cannot find such a functionality? I have tried standard Material ui grid, but it is not working.
What you're looking for is called a masonry grid. It's currently impossible to do so in pure CSS, even with the new grid layout mechanism ([1], [2]).
Material UI doesn't offer an out-of-the-box solution for masonry grids.
You might be interested in some of the many JavaScript libraries which arrange elements this way using a custom script. The most popular one which immediately comes to mind is Masonry Desandro. An alternative is Isotope, a payed library for commercial use, which also has a mode for masonry layout.

Handle long time sorting in ag-grid (pure JS)

I am working with a big amount of data (1M - 5M), and rows in the grid should be groupable, sortable, and filterable. As ag-grid can populate table with data quickly enough, I use in-memory row model to satisfy requirements.
However, when I click column in order to sort all rows by this column, it takes some time to do this. Moreover, sequential clicking on columns while rows are still being sorted may crash grid as well as browser application.
Are there any ways to prevent user from clicking on columns (disable sorting, show loading overlay, or something like this)?
I am trying to use beforeSortChanged and afterSortChanged events to show overlay or modify DOM elements (to make grid a little bit grey and show loading circle), but it doesn't work properly: beforeSortChanged event handler seems to be stuck for a moment and then only executed.
Ag-grid is used inside Ember framework as a component.
How about using onCellClicked which is an attribute of the columnDefs. Should work in a similar manner to what you are looking for with beforeSortChanged.

Displaying sub-data rows inside a row in SlickGrid Table

I've started using SlickGrid and have to implement a kind of functionality where I need to show sub-row inside a parent row of SlickGrid.
Here's the scenario
Here's Asia, Europe is having sub categories in Services Column and these service columns are expandable/collapsible
I'm trying to customize this for first column.
Is any other link/source available to refer to accomplish the feature.
Are you aware of the grouping/aggregates example ?
http://mleibman.github.io/SlickGrid/examples/example-grouping
This offers very similar behaviour, but the exact 'cell-merging' behaviour you show is not currently available in SlickGrid. Slickgrid tends to use tree structures rather than a flat structure. That said, it may not be too hard to hack up, but it seems everyone wants a different visual layout and it becomes very hard to support them all.
If you don't need editing or scrolling, I'd suggest this would work best as an HTML table, or even a PDF.

Angular ng-grid/ui-grid implementing view logics inside views

I am trying to create grid with advanced features(filter, re-sizable, scrolling, fixed header, row formatting, cell formatting) using angular js. I have read the following grids documentation.
ng-grid
ng-table
smart-table
And, ng-grid has many features and perfect for our requirements. but I want the following 2 options also. is it possible to achieve from ng-grid?
Formatting
We have number of columns in my grid (approx 40). Most of the column data need to be formatted in cell. for eg: Adding link, change date format, Reducing length of the content with tooltip..etc., Here, I can not do this stuff inside views. But this one is handled perfectly in ng-table.
If I can not do this in view, then my javascript (using callbacks) code is going to be increased. I don't want this way because angular perfectly do dynamic views.
Also, I want Header formatting, filter formatting, row formatting should be done inside views.
Responsive using Bootstrap
Our application should work in all devices. but ng-grid not working as responsive if I view my application in tablet devices.
I'm working on the following grid angular grid - has the features you mention. Similar to ui-grid in it's basic interface, but approaches things differently, including how the grid is customized. You can add css styling at the column and cell level, as well as providing your own custom cell renderers for complete control.
Asik,
The project Angular-UI renamed the ng-Grid to UI-Grid and the website changed to http://ui-grid.info.
Now it's pure AngularJS, without jQuery, use Bootstrap 3 LESS and it's full features that fill your requirements.
Take a look in the page of Tutorials to check the power of features.

Javascript widget inspired by iPhone UITableView?

Cocoa Touch's UITableView allows a user to scroll through large numbers of data rows with good performance because it recycles table rows. Rather than create a GUI element for every single data row, a limited number of table rows is created, and simply updated with the relevant data as the user scrolls, giving the illusion of navigating up and down a very large number of table rows.
Has anyone seen this done in javascript? Is there a plugin available anywhere that will do this for me?
infinity.js works well. It will dynamically load 'pages' behind the scenes giving you the appearance that the list has been fully loaded.
More information can be found on their Github page - https://github.com/airbnb/infinity
Additionally, I've forked the project updating it to work with Zepto. I also set it up to use any scrollable div (set up with overflow: scoll) with the class 'scrollable' - https://github.com/elliotcw/infinity
I should add that I made these changes as this is great for large lists on mobile devices, which slow down when you have to many complex elements on the page.
I was looking for this as well, and infinityjs [1] doesn't seem to quite mimic the same interface as UITableView. And it was a problem for my scenario that infinityjs required that the element containing the list items already be added to the DOM.
MegaList [2] came closest to what I wanted. Andrew (author) has done a great job of designing it for mobile first, with touch support etc. One caveat for me was that it appears to assume a strict selection list model and does a little bit more than I'd like a list component to do (e.g. binding to resize events and trying to handle that automatically).
So I started writing a barebones list component, also modeled after the iOS UITableView. It's a work in progress and I'm putting in just what I need. Sources are here https://github.com/shyam-habarakada/js-virtual-list-view. I'm putting in just what I need as I go, and contributors are needed :-)

Actually the algorithm is not difficult at all. If you know javascript you should be able to write this. The algorithm only needs the height of a cell and the height of the table.
I only know these two:
Apple's Dashcode javascript Framework has an implementation of a Table. You could take a look and see if that is what you need.
Or Cappuccino Framework which is basically Objective-J but behind the scenes is Javascript.
Clusterize.js does exactly that.
It's small and works with any tag (table, lists, divs)
