Creating a $show conditional

[mikesz]

Hello,

I would like to know the specifics of how to ceate a $show conditional. For example:

<if condition="$show['editor_css']">
$editor_css
</if>


The critical question is where do I define the array element and assign the value.

Any clues gratefully accepted.

TIA, mikesz
