There are currently 6 tabs and I am considering adding another 4 more. However, I hope to have it in 2 rows. Please see a screenshot below to illustrate what I mean.
Not sure what your question is.
If you would like to have more tab-links and they should go to a second row, you can set the parent - “tabs menu” to Flex Children - Wrap.
This will place new tab-links to the second row when there’s no space in the first row.
