A script for an accessible accordion tabs component

a11y-accordion-tabs's Issues

Deeplinking addon?

Would it be possible to have a deeplink option with this tab set?

Clicking on the tab would add the hash to the end of the url. Like example below:

site.com/#tab-04
This would bring you directly to the 4th tab in the set?

Any benefit to this compared to pure HTML/CSS solutions?

I'm just curious if there are any specific accessibility benefits to your script over something like this:

https://codepen.io/impressivewebs/pen/qBNqGbE

Which I created a short while back and which doesn't use any JS. It seems like it basically works the same way with the keyboard navigation...?

Can you support using data attributes?

Thanks for the great work. Can or does it support using data attributes to change settings? For instance when you use the Slick Slider js, you can add data attributes for specific settings like:

I would like to change/call settings straight from the html.

Thank you once again for this.

Tabs start expanded with accordion start collapsed?

Can there be separate collapsible options for the tabs vs accordions? I would like the tabs to always start expanded and the accordion to start collapsed. I only see a global startCollapsed property. Thanks!

Support for multiple a11y tabs in the same page, parent tabs loaded when child tabs are clicked

Hello,

I would like to implement child tab inside a parent tab, as below, however when the child tabs are clicked the parent tabs are loaded.

Does a11y support this functionality?

Any particular reason Accordion is misspelled as accordeon?

In documentation and in the library itself, accordion is misspelled as accordeon in class names accordeon-trigger js-accordeon-trigger Is there an intentional reason for this?

Multiple accordions on same page, setting data-default produces weird results

I have multiple accordions on the same page. If one of them has data-default attribute set, so that the first item in it auto opens, all subsequent accordions will also show the same behavior, even if the data-default attribute is not present on them.

Is JS needed ?

We can easily achieve the same functionality with only HTML / CSS :

But how about a11y then ?
Most important : Happy holidays ! 🎄

tabs to no effect

please help me！！

Stop playing videos when changing a tab

Hi. Firstly thank you for the great plugin.

There are different types of embedded videos under each tab content including html5 video and youtube iframe.
If one video starts playing it continues playing in the background anyway even if I change a tab.

Could you please advise what would be the best solution in this case?
