How to code a simple show/hide chunk via a checkbox

Hi Folks

All I'm trying to create is a TV consisting of a couple of check boxes;
one marked 'on' and one 'off', which when selected,
will show/hide a small chunk of html.

I could only find this thread from some eight years ago...
https://forums.modx.com/thread/9799/toggling-a-chunk-on-and-off-tv-problems
But I was wondering if there is any more recent development.

The 'ToggleTVSet' Extra seems a little overkill just to add/remove what is basically a <p> tag.
That said, maybe creating two TV's that can be selected accordingly may be the way forward.

Any suggestions as to how perhaps I should begin thinking around this
would be much appreciated.

Many Thanks
Chris

I'm using:
MODX 2.5.1
MAMP (latest (3.0.7.3))
PHP (5.5.18)
MySQL (5.5.38)
Chrome: Std and Canary (latest versions)
Mac OX (Mountain Lion-10.8.5).

I would guess this would work..

Create a template variable and then if checked display the chunk.

[[*templateVariable:notempty=`[[$chunk]]`]]

You could also do it with a short snippet:

$show = $modx->resource->getTVValue('TvName'); 

if (!empty($show)) {
    return $modx->getChunk('ChunkName');
} else {
    return "";
}

Thanks Guys

I'm aware that there are many ways of doing the same thing in modx.
I'm therefore in the throes of getting to grips with the possibilities of combining TV's, snippets and chunks,
and what might be the most efficient ways in which to utilise these building blocks.

I have tried both suggestions and indeed, after a little tweaking, get the results I'm after.
Basically I'm trying to create an on/off switch that displays/hides an occasional discount callout.
So in the interest of my learning, how does the following stack up in terms of understanding/efficiency?

TvName > Input Type : Radio Options  
Input values : No==[[$chunk]]||Yes==[[$chunk_with_discount]]  
default: No==[[$chunk]]

Template call: [[!*TvName]]

Any feedback would be great

Many Thanks

I think the snippet would be slightly faster, but the difference is probably small and the convenience of the radio options is nice to have.

The snippet could be made to work with the radio options, but I'm not sure it's worth the trouble.
