Well, this is the most basic usage of the plugin:
<a href="#" showhide="1stID">
This is 1st Show-Text, This is 1st Hide-Text
</a>
<div id="1stID">
1st Text.
</div>
Unfortunately, adding more instances just breaks it.
<a href="#" showhide="2ndID">
This is 2nd Show-Text, This is 2nd Hide-Text
</a>
<div id="2ndID">
2nd Text.
</div>
Doing this, “This is 2nd Show-Text, This is 2nd Hide-Text” appears in plain text, followed with “2nd Text” not hidden but clearly visible.
