Questions tagged [angular-material-8]

Angular Material2 is an implementation of Material Design in Angular. This tag is for version 8.x of Angular Material2. Do not use this tag for other versions (e.g. v6, v7) or for AngularJS Material (the implementation of Material Design for the older AngularJS framework).

Usage

  • This tag is intended for questions which ask about Angular Material2 v8.x
  • Please take note that you should use the tag for AngularJS 1.x Material questions instead of this tag.

Goal

Taken from the official repo:

Our goal is to build a set of high-quality UI components built with Angular and TypeScript, following the Material Design spec. These components will serve as an example of how to write Angular code following best practices.

Asking a question

  • Mention the versions of Angular and Angular Material2 that you're using.
  • Reduce your issue to a small example
  • Post a reduced working code on stackblitz.com
  • If there's a bug (or some unintentional behavior), try to troubleshoot the problem. (If it's a bug report, please create a new issue at Angular Material2's Github repository instead.)
