The normal use of the Select tag is not all level, like this.
But column classification is a class two classification
I used to do this.
In the Column category page is the CSS control to show whether it belongs to the superior category and then control the distance level 2 classification a distance of 3 Class A distance
Can't you just show up in select?
Not the same as the Linkage menu.
Or simulate a drop-down menu with JS?

Ask the great God to give an example of the idea or something
How does the general design do this classification display?
