javascript - Can AngularJS directive ngOpen be used for an accordion component? -


what point of angularjs directive ngopen aside using details tag?

i'm trying create accordion component , came not sure if helps considering haven't been able use other details tag.

<body ng-app="">     check me check multiple: <input type="checkbox" ng-model="open"><br/>   <details id="details" ng-open="open">      <summary>show/hide me</summary>   </details> </body>

the purpose of ngopen directive preserve open attribute, used details element.

from docs:

the html specification not require browsers preserve values of boolean attributes such open. (their presence means true , absence means false.) if put angular interpolation expression such attribute binding information lost when browser removes attribute. ngopen directive solves problem open attribute. complementary directive not removed browser , provides permanent reliable place store binding information.

neither open nor details specific angular. valid html:

<details open>     <summary>section header</summary>     section content </details>

angular added ngopen binding.

note: experimental feature , not supported in browsers

p.s. if you're looking implement accordion or collapse functionality, recommend using bootstrap ui offers angular directives both work across browsers.
