Hello, and thank you for using my plugin!
I see what you mean and I’m going to add this in the next update. though I will wait a bit before publishing a new version, in order to see if there is the need of any bug fix or other small features addition.
In the meanwhile, if you’re going to use the widget with the same introduction text for each place where you put it, you can easily customize the output template file.
you’ll need to access your site files (with ftp by instance). then browse the folder:
wp-content/plugins/wp-list-pages-by-custom-taxonomy/templates
copy the file:
pbytax_template.php
and put the copy into your theme folder (something like wp-content/themes/your-theme-name/ )
edit this copy and scroll down till you see this comment
//// THE LOOP STARTS HERE,
// HERE YOU COULD EDIT THE HTML STRUCTURE OF THE OUTPUT
go down a couple of lines, and add whatever you want just above the line where you see:
<select class="pbytax-dropdown" id="pbytax-selector" onchange="location = this.options[this.selectedIndex].value;">
everything placed above that line, and after the ?> will be printed just above the dropdown.
I suggest to wrap your text into a -p- tag, like:
<p> Your introduction text here </p>
let me know if you managed to do it or need more help
cheers!
