I tested this in my test wiki (DokuWiki-on-USB-stick) and I found this might be a problem with how the Bootstrap Affix Plugin is integrated into the bootstrap3 template, see in the code here:
https://codesearch.dokuwiki.org/xref/template/bootstrap3/script.js#811
This function causes the TOC to be closed when half way scrolling down. Which is annoying because you have to click on the TOC toggle to open it up again.
When you comment out this function in /dokuwiki/lib/tpl/bootstrap3/script.js
, as follows, it stops this shutting down behavior and works just fine:
$dw_toc.on('affix.bs.affix', function () {
// dw_template.tocClose();
});
PS: Sorry, der Chat war ja auf Deutsch, naja ich denke ihr versteht es trotzdem.
Cheers!
