    Thank you for creating such a wonderful WordPress plugin. I love Zotpress.
    I understand that using custom CSS I can customize the bibliography on my webpage. However, I would like to hide the abstract initially, and then when a visitor clicks on show abstract then it should be visible. For this purpose, I am trying to filter the content of the [zotpress] shortcode, however, a simple filter does not work. I tested the same code it does work on the other content on the same page.

    
function za_zotpress_shortcode_filter($output, $tag, $atts, $m) {
	if ($tag === 'zotpress') {
		return str_replace("Abstract", "New Abstract", $output);
	}
}
add_filter('do_shortcode_tag', 'za_zotpress_shortcode_filter', 10, 4);

    Thank you very much, any help will b highly appreciated!!

    I think you could do the hiding and showing with CSS alone along the lines of this solution: https://dabblet.com/gist/1506530

    So you’d load all of the abstracts without filtering, then display:none with CSS, and use a toggle to set the display status. This would require no filtering at WordPress level.

    Thanks for the reply, Mark. Thanks for the link to the CSS trick. If I understood it correctly then this way I will be able to show/hide all of the abstract simultaneous, not a particular one. I want to show a link (Show Abstract/Hide Abstract) for each of my publications in the bibliography. I like the plugin because it very powerful particularly at the backend it does a very nice job. However, at the front end, I am not satisfied so I wanted some tweak.

    No, it can also be at the level of abstract, as there is no limit to the amount of toggles you can have. E.g. the toggle could be a placeholder “Abstract”.

    I suppose folks more well-versed in Javascript could also fix it that way; it doesn’t need to be CSS. The main thing I’m saying is that it’s probably not a great idea to do it at the level of WordPress content filters, as they necessitate a new database query (and hence page load) every time a new abstract is needed; whereas loading them all at once and then manipulating their visibility is going to be faster, easier to cache, etc.
