Include md-optgroup label in md-select selected item #5605
Description
Bug, feature request, or proposal:
Feature request
What is the expected behavior?
When md-select has some md-optgroup's there might be some options that have the same label. For instance:
Cars
|
| --- SUV |
|---|
| --------Diesel |
| --------Petrol |
| --- Mini |
| ---- |
| --------Diesel |
| --------Petrol |
It should be nice if the selected value (when the dropdown is closed) also included the option group label, like SUV-->Diesel
What is the current behavior?
Only the option label is shown
What are the steps to reproduce?
Use the md-select with some md-optgroup's
What is the use-case or motivation for changing an existing behavior?
I know this is the default select behavior, but I might see a usability improvement here.
Which versions of Angular, Material, OS, TypeScript, browsers are affected?
All
