Mike,
An action cannot directly contain wikitext that should appear -- it can
generally only contain action widgets (there are a few exceptions, like you
can use a list widget to create a bunch of actions matching some pattern).
The general pattern for creating a button that hides/shows content is to
create a field that contains information about whether or not to show the
content, then use a $reveal or $list widget to control whether it appears.
For instance, to use a field called "show-content" on the current tiddler
to control the display:
\define show-actions() <$action-setfield show-content="yes"/>
\define hide-actions() <$action-setfield show-content="no"/>
<$reveal state="show-content" type="match" text="yes">
<$list filter="[tag[About]]">
<$link/>
{{||$:/core/templates/static-tiddler}}
</$list>
<$button actions=<<hide-content>>>Hide me again</$button>
</$reveal>
<$reveal state="!!show-content" type="nomatch" text="yes">
<$button actions=<<show-content>>>
Click me!
</$button>
</$reveal>
(Note that unlike in your example, I've included an action and button to
hide the content again. You can of course take that out if you don't want
it...but the only way to get the content to go away again will be to go in
and manually change the field on the current tiddler.)
You might also like to use a temporary tiddler, rather than a field on the
current tiddler, to store whether the content should be open. If so, you
would do something like:
\define show-actions() <$action-setfield $tiddler=<<qualify
"$:/temp/MyContentIsOpen">> show-content="yes"/>
<$reveal state=<<qualify "$:/temp/MyContentIsOpen">> type="match"
text="yes">
<<qualify>> may not be necessary depending on your use case -- it prevents
name collisions if you use this as a template on multiple tiddlers
(otherwise, clicking the "show" button on one tiddler that uses the
template will result in the content showing on all of them).
