How to display silo structure in worpress site like an arrow.

any one knows how to display like this
main>sub1>sub2

instead of main/sub1/sub2 in search results.

Also how to display first format, to show above the post in wordpress.
for example

main>sub1>sub2
TITLE
post

so if some one clicks sub1.. it will automatically go to sub1.

Sorry I dont have much knowledge in silo.. So please help me.

What about using some plugins in wordpress directories? the free ones can do this.
