Hi, I'm trying to set up a page on my site with collapsible content displayed using an accordion. I found some code at w3schools which works well. However, I would like to link to and open particular accordion content on the page using an external link with anchor text, but can't figure out a way to do it. I've tried various coding solutions that I found online but nothing seems to work. Can anyone suggest a solution?

Richard.

Post a link to the w3schools page and I'll take a look to see if I can see a way to link...

Hi Richard, I believe the trick will be to write the link with a javascript onclick event to do what the code does to the menu.

If you go back to that page https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_accordion_symbol
Add the following just above the closing body tag

<script>
function menulinkopen(mnuitm) {
document.getElementsByClassName("accordion")[mnuitm].classList.toggle("active");
var accrdnxt = document.getElementsByClassName("accordion")[mnuitm].nextElementSibling;
accrdnxt.style.maxHeight=accrdnxt.scrollHeight + "px";
}
</script>
<div style="margin-top:30px;"><button onclick="menulinkopen(1)">Open 2nd the Menu item</button></div>

</body>
</html>


Now click the RUN button and you will see my button appear and clicking it will open the 2nd accordion.

To use this on your site, just use the function as it is and place that at the bottom of your bage before the closing </body> tag.

Then create your link.
<button onclick="menulinkopen(1)">Open 2nd the Menu item</button>

The key here though is the number placed in the function call.
Most all computer code starts counting at zero, so a zero there will trigger the first accordion, a 1 the second, and a 2 the third and so on.

Anyway, that should work for you and let me know how you get along.


Thanks,
David

Hi David,

Thank you for the code suggestion provided. I tried this and it works for the button on page, but I wanted to link to the accordion content page from another page. For example, a link to www.myurl/accoardionpage.php#anchor. Can this or any other solution be used like this?

Richard.

Hi Richard, sure anythings possible as they say.
I can think of several ways to do this, but maybe it's best to send me a message (click my user name) and links to the pages and I'll see what I can whip up.
