Tabs on Stat Blocks.

I've seen Homebrew Stat Blocks with smaller boxes on them that I've seen people call tabs. I can't seem to add tabs to my Homebrew Stat Blocks on D&D Beyond. Could someone help? Reddit - https://preview.redd.it/ol2412dwqrl21.jpg?auto=webp&s=7e7f9ad3b98dbb234bfae1d5796cb32b764109b9. The white box in the attached image is what I am referring to.

 that was done either in homebrewery or gmbinder, not on DDB

Thank you! ... Why isn't it a feature on here??
