MD Data Table doesn't come with a master - detail setup. At the time of this post AM2 Data Table has been out for only 3 weeks. There have been a few questions around the Web regarding how to setup the Data Table for master - detail uses. I struggled with it for a while until I figured it out.
Some posters on various sites such as the Data Table's GitHub site would like to be able to click on a row and the rows below slide down to reveal a little data. The Data Table doesn't natively do that and won't for a while.
However, for viewing large amounts of data or editing then buttons and separate views are good. So how to implement this?
