Is there a way to get WebOstorm tag attribute values ​​for autocomplete?

Question

I am trying to make WebStorm autocomplete some HTML attribute values ​​when working with Angular Material.

Editor> Inspections> HTML> Unknown HTML tag attribute

I added some attributes here like flex , flex-md and layout , but how can I get auto-completion for the situation as shown below?

 <div layout="can be row or column"></div> 

The layout value is row or column , so I want the row and column to appear when I enter the layout = "row / column here", is this possible?

I am using WebStorm 12 EAP.

I also did some research, but did not answer this question. It looks like you can just add a custom tag that will be automatically completed, for example. to layout="" , but not their meaning.
You cannot change the completion behavior at the moment, see this old ticket

Well, you can try importing. In the context of TypeScript, WebStorm can generate import statements for modules, classes, and any other character that can be exported and called as a type.

Here is the link from the official documentation.
