The first problem is that you can't nest macros, so you can't put
<<moredetail >> *within* the parameters of a call to <<moredetail>>.
However, it *is* possible to implement a "nested reveal" in TW5, though the
syntax is probably not quiet as simple as you want.
Try this:
\define b(s,t)
<$reveal type="nomatch" text="show" state="$:/state/$s$">
<$button class="tc-btn-invisible" tooltip="more details">
<$action-setfield $tiddler="$:/state/$s$" text="show"/>
$t$
</$button>
</$reveal>
<$reveal type="match" text="show" state="$:/state/$s$">
<$button class="tc-btn-invisible" tooltip="less details">
<$action-deletetiddler $tiddler="$:/state/$s$"/>
$t$
</$button>
</$reveal>
\end
<<b 1 "I went to the store...">>
<$reveal type="match" text="show" state="$:/state/1">
<<b 2 "It was raining so I decided to drive instead of walk...">>
<$reveal type="match" text="show" state="$:/state/2">
The car took a while to start since it was so cold.
</$reveal>
<<b 3 "I arrived at 5pm...">>
<$reveal type="match" text="show" state="$:/state/3">
It was Sunday so they were just closing up.
</$reveal>
</$reveal>
<<b 4 "Then I bought a tomato...">>
<$reveal type="match" text="show" state="$:/state/4">
It was delicious.
</$reveal>
The macro <<b>> outputs text that is a "show/hide" toggle. It uses
$:/state/xxx to track when the details are shown, and then *removes*
$:/state/xxx when the details are toggled closed. This avoids an
accumulation of random state tracking tiddlers. Note also that $:/state/*
tiddlers are 'system' tiddlers, so they don't appear in the sidebar (except
in the "more>system" tab, of course). This avoids the ugliness of seeing
them appear and disappear as you toggle the text.
Let me know how it goes...
