I am using Ignite UI "igniteui-angular": "6.1.1" at that time grid filter design is like below

But when i updated Ignite UI version "igniteui-angular": "6.2.x" then design is changed

but i want to use this version "igniteui-angular": "6.2.x", with old filter design, so how can this possible?
@nikunjgajera Hi, all version after 6.2.x are using the new design of the filtering you can't go to the old one after this.
@nikunjgajera We're currently working on an excel-style filter UI, in addition to the current filtering row. As soon as the spec is made available in our wiki, I will update the issue with a link, so you can see it. We're planning to make it swappable with the filter row.
@nikunjgajera here is the spec closing this one you can follow on the Excel Style filtering issues:
