HTMLDetailsElement: name property
The name property of the HTMLDetailsElement interface reflects the name attribute of <details> elements. It enables multiple <details> elements to be connected together, where only one for the <details> elements can be open at once. This allows developers to easily create UI features such as accordions without scripting.
The name attribute specifies a group name — give multiple <details> elements the same name value to group them. Only one of the grouped <details> elements can be open at a time — opening one will cause another to close. If multiple grouped <details> elements are given the open attribute, only the first one in the source order will be rendered open.
Value
A string. The empty string if the element is not part of any group.
