Hi Experts,
I asked for a solution to have a horizontal table of content here : Table of content horizontal - #6 by stefan_from_germany
and Talk TW - Community discussion forum about TiddlyWiki found a solution.
I do really don’t know how it works what Brian is doing in the macro 
.
For testing I used the macro in tiidlywiki.com with the examples used in the table of content and this was the result.
I have an idea for improvement of this outstanding realisation.
Is there a small chance to change the code in this way that only one table of content is open at the same time?
Example:
I press open the First
And if I now open the Second
The First will be closed and the Second opened
Hopefully it is possible ( 
maybe also an idea for the standard toc )
Thx in advance
Stefan
