# angular-material-expansion-panel

A module that implements design elements based on [Material Design](https://material.google.com) [Expansion Panels](https://material.google.com/components/expansion-panels.html). With additional features that are similar to Google Inbox style Expansion Panels.

To see Material Design Expansion Panels Specification go [here](https://material.google.com/components/expansion-panels.html).

The expansion panel component can be used with just html or you can use the Expansion Panel Group to control multiple panels through code
