How to implement Live Template in WebStorm?

Question

webstorm

Hello! Who fumbles in WebStorm?)
In general, I created a Live Template for myself on media query

like this

When using it: @m + Tab
it works

in the following way

But I would like that when @m + Tab is called, the cursor is placed on the value 768, but the dropdown sheet with values ​​​​is immediately displayed

similar to here

Only the values ​​were those that I will indicate myself:
For example:
"320",
"576",
"768",
"992",
"1200"
and so on.
Could you tell me how to organize this template correctly? Googled, read the documentation on creating a live Template, but didn’t understand the principle of implementation.

Answer 1

specify expression: enum("320", "576", "768")
however, collisions are possible there, for example, it works for me in css, but not in scss - the popup blinks and immediately closes
