Thanks, David. I think I’ve already read that, but I’ll take another look.

I agree about the design (I didn’t set up this template), and I’m going to try to persuade my client to ditch those leading zeros. But in the meantime my hack with the hidden numbers is working. Just haven’t checked yet what it will do when I try to create an accessible PDF…

This project is stretching my InDesign brain in other ways too. We have references (bibliography) in as numbered endnotes, but some refs need to be cited more than once. In the past they resorted to static notes, but we now want them to be clickable in the PDF. So far I have a combo of endnotes and cross-references for the duplicates. But it’s all fun working this out.

I’ve thought of another fudge that works, but still interested to hear whether anyone has a better solution.

I’ve set the level 1 numbering to 1,2,3,4 format but applied a character style to the numbers that’s a tiny size and no colour. And for the visible section number I’ve created a separate unthreaded frame with just the 01,02,03 etc numbers so that they appear on the page but are not part of the multilevel list.

Thanks very much for looking, Steve. I think that was just a mistake by me in setting up the test file. It’s not like that in my original (the character style only applies to the box characters). However, I’ve fixed the test file and tried again and I’m still getting the different sized boxes in Kindle Previewer. So I’m flummoxed :-)

No, can’t share it sorry. I guess I could create a new doc with some random text to replicate the problem.

Okay, see if this works :-)

Thanks, David. I had a swift response direct from Kerntiff, and alas it doesn’t work in the latest Indd.
