First line showing code

check your your page in the TEXT not VISUAL mode of the editor.
Sounds like you copy-pasted somethign in Visual mode and it brought wiht it some formatting (font, color, etc) that is breaking the shortcode. You should be able to see the issue and fix it in Text mode.

I’m pretty sure I was looking at the text editor. This is what I see there now:
[expand?tag="div"?title="<strong>Should I manage my own property?</strong>"]Most rental housing investors consider...

This is the code showing for another faq that isn’t showing code:
[expand tag="div"?title="<strong>What areas do you serve?</strong>"]We serve greater Placer County and select areas...

The whole section of faq’s on this page is wrapped in a div, but that shouldn’t cause this, right?

try this:

[expand tag="strong" title="Should I manage my own property?"]

see what we did there?

Hi Baden! That does solve my code shwowing issue, but I had been using the
tag="div"
to solve the wpautop issue.

I’ve tried moving around the p tags, I’ve added the filter for execution priority of wpautop to functions.php, and the entire FAQ was already wrapped in a div. I also tried the workaround at the bottom of this thread to display br none.

Suggestions?

My code looks like this:

If you need to use div and have the triggers bold, then you need to use the trigclass attribute and define your own class:

[expand tag="tag" trigclass="my_trigger_class" title="Should I manage my own property?"]

CSS:

.my_trigger_class {
     font-weight: bold;
}

sorry, tag=”div” in the example above:

[expand tag="div" trigclass="my_trigger_class" title="Should I manage my own property?"]
