When using VoiceOver, I'm able to send a click event (VO+Space) to an element with the role="combobox" attribute only when it does not have the aria-expanded attribute. Once the attribute is set, regardless of its value, the click action does not work. I'm able to send the click event for comboboxes with aria-expanded in Chrome and Firefox. See the live example of a select only combobox in the ARIA authoring practices- https://www.w3.org/TR/wai-aria-practices-1.2/examples/combobox/combobox-select-only.html If you remove the aria-expanded="false" from the element in the web inspector and try sending the click- it will work- the listbox popup will expand. Some other notes: - it seems that Safari is treating an element with role="combobox" and aria-expanded="false" as if it was expanded as it begins the announcement with the word "confirm", - aria-expanded is a required state as per the ARIA spec (https://www.w3.org/TR/wai-aria-1.1/#combobox) meaning that it must be present at all times - the issue will be highly problematic once ARIA 1.2 turns into a recommendation (currently in candidate recommendation meaning it is close to become the spec) as 1.2 officially acknowledges comboboxes as select-only and text field comboboxes whereas previous versions were treating this element as if it always had to have a text box. Alos, see the attached aria-ExpandedComboboxIssue.html file that shows the issue but displaying the system alert dialog on click. 1843828 1 webkit-bug-importer 2022-02-19 04:21:01 -0800 <rdar://problem/89185255> 1843830 2 452636 aron_j 2022-02-19 04:22:19 -0800 Created attachment 452636 Text case for the aria-expanded issue on elements with role="combobox" 1843832 3 aron_j 2022-02-19 04:25:12 -0800 *** Bug 236880 has been marked as a duplicate of this bug. *** 2055936 4 peter.hudak 2024-08-28 07:21:19 -0700 Hi Safari Dev Team, Could you please provide an update on when the bug with the Safari and VoiceOver combination affecting the combobox ARIA role might be fixed? This issue is impacting accessibility, and any timeline or information would be greatly appreciated. Thank you! Peter Hudak 2128695 5 aronjanecki 2025-07-09 08:05:23 -0700 This issue is fixed. It's not possible to send the click event when aria-expanded is set to false but this is understandable, all fine when aria-expanded is set to true. 452636 2022-02-19 04:22:19 -0800 2022-02-19 04:22:19 -0800 Text case for the aria-expanded issue on elements with role="combobox" ariaExpandedComboboxIssue.html text/html 2771 aron_j PCFET0NUWVBFIGh0bWw+CjxodG1sIGxhbmc9ImVuIj4KPGhlYWQ+CiAgICA8bWV0YSBjaGFyc2V0 PSJVVEYtOCI+CiAgICA8bWV0YSBodHRwLWVxdWl2PSJYLVVBLUNvbXBhdGlibGUiIGNvbnRlbnQ9 IklFPWVkZ2UiPgogICAgPG1ldGEgbmFtZT0idmlld3BvcnQiIGNvbnRlbnQ9IndpZHRoPWRldmlj ZS13aWR0aCwgaW5pdGlhbC1zY2FsZT0xLjAiPgogICAgPHRpdGxlPkNvbWJvYm94IGFuZCBhcmlh LWV4cGFuZGVkIGlzc3VlPC90aXRsZT4KICAgIDxzdHlsZT4KICAgICAgICBrYmQgewogICAgICAg ICAgICBiYWNrZ3JvdW5kLWNvbG9yOiAjZWVlOwogICAgICAgICAgICBib3JkZXItcmFkaXVzOiAz cHg7CiAgICAgICAgICAgIGJvcmRlcjogMXB4IHNvbGlkICNiNGI0YjQ7CiAgICAgICAgICAgIGJv eC1zaGFkb3c6IDAgMXB4IDFweCByZ2JhKDAsIDAsIDAsIC4yKSwgMCAycHggMCAwIHJnYmEoMjU1 LCAyNTUsIDI1NSwgLjcpIGluc2V0OwogICAgICAgICAgICBjb2xvcjogIzMzMzsKICAgICAgICAg ICAgZGlzcGxheTogaW5saW5lLWJsb2NrOwogICAgICAgICAgICBmb250LXNpemU6IC44NWVtOwog ICAgICAgICAgICBmb250LXdlaWdodDogNzAwOwogICAgICAgICAgICBsaW5lLWhlaWdodDogMTsK ICAgICAgICAgICAgcGFkZGluZzogMnB4IDRweDsKICAgICAgICAgICAgd2hpdGUtc3BhY2U6IG5v d3JhcDsKICAgICAgICB9CiAgICAgICAgY29kZSB7CiAgICAgICAgICAgIGNvbG9yOiAjMDM2Owog ICAgICAgICAgICBmb250LXdlaWdodDogNzAwOwogICAgICAgIH0KICAgIDwvc3R5bGU+CjwvaGVh ZD4KPGJvZHk+CiAgICA8aDE+Vm9pY2VPdmVyIGNsaWNrIGRvZXMgbm90IHdvcmsgb24gY29tYm9i b3hlcyB3aXRoIGFyaWEtZXhwYW5kZWQ8L2gxPgoKICAgIDxwPlRlc3QgY2FzZSBkZXNjcmlwdGlv bjo8L3A+CiAgICA8dWw+CiAgICAgICAgPGxpPgogICAgICAgICAgICBFYWNoIGNsaWNrIGV2ZW50 IHNob3VsZCB0cmlnZ2VyIHRoZSA8Y29kZT5hbGVydCgpPC9jb2RlPiBtZXRob2QgYW5kIGNoYW5n ZSB0aGUgdmFsdWUgb2YgdGhlIDxjb2RlPmFyaWEtZXhwYW5kZWQ8L2NvZGU+IGF0dHJpYnV0ZSBv ciBzZXQgPGNvZGU+YXJpYS1leHBhbmRlZDwvY29kZT4gaWYgbm90IHByZXNlbnQuCiAgICAgICAg PC9saT4KICAgICAgICA8bGk+CiAgICAgICAgICAgIEluaXRpYWxseSwgdGhlIHNlY29uZCA8Y29k ZT4mbHQ7YnV0dG9uJmd0OzwvY29kZT5lbGVtZW50IHdpdGggPGNvZGU+cm9sZT0iY29tYm9ib3gi PC9jb2RlPiBjYW4gYmUgYWN0aXZhdGVkIHVzaW5nIDxrYmQ+Vk8gKyBTcGFjZTwva2JkPi4KICAg ICAgICA8L2xpPgogICAgICAgIDxsaT4KICAgICAgICAgICAgT25jZSB0aGUgPGNvZGU+YXJpYS1l eHBhbmRlZDwvY29kZT4gaXMgc2V0IG9uIHRoZSBjb21ib2JveCB0aGUgPGtiZD5WTyArIFNwYWNl PC9rYmQ+IGNsaWNrIGV2ZW50IGlzIGJsb2NrZWQgaW4gU2FmYXJpICh3b3JrcyBpbiBDaHJvbWUg YW5kIEZpcmVmb3gpLgogICAgICAgIDwvbGk+CiAgICA8L3VsPgoKICAgIDxkaXY+CiAgICAgICAg PGJ1dHRvbj4KICAgICAgICAgICAgQWxlcnQgMQogICAgICAgIDwvYnV0dG9uPgogICAgPC9kaXY+ CgoKICAgIDxkaXY+CiAgICAgICAgPGxhYmVsIGZvcj0iY29tYm8iPkFsZXJ0IDI8L2xhYmVsPgog ICAgICAgIDxidXR0b24gaWQ9ImNvbWJvIiByb2xlPSJjb21ib2JveCI+Tm8gb3B0aW9uczwvYnV0 dG9uPgogICAgPC9kaXY+CgoKICAgIDxkaXY+CiAgICAgICAgPGJ1dHRvbj5BbGVydCAzPC9idXR0 b24+CiAgICA8L2Rpdj4KCgoKICAgIDxzY3JpcHQ+CiAgICAgICAgY29uc3QgYnV0dG9ucyA9IEFy cmF5LmZyb20oZG9jdW1lbnQucXVlcnlTZWxlY3RvckFsbCgnYnV0dG9uJykpOwoKICAgICAgICBj bGFzcyBBcmlhRXhwYW5kZWRJc3N1ZSB7CiAgICAgICAgICAgIGNvbnN0cnVjdG9yKG5vZGUpIHsK ICAgICAgICAgICAgICAgIHRoaXMubm9kZSA9IG5vZGU7CiAgICAgICAgICAgICAgICB0aGlzLmFk ZENsaWNrRXZlbnQoKTsKICAgICAgICAgICAgfQogICAgICAgICAgICBhZGRDbGlja0V2ZW50KCkg ewogICAgICAgICAgICAgICAgdGhpcy5ub2RlLmFkZEV2ZW50TGlzdGVuZXIoJ2NsaWNrJywgdGhp cy5oYW5kbGVDbGljay5iaW5kKHRoaXMpKTsKICAgICAgICAgICAgfQogICAgICAgICAgICBoYW5k bGVDbGljaygpIHsKICAgICAgICAgICAgICAgIGFsZXJ0KHRoaXMubm9kZS50ZXh0Q29udGVudCk7 CgogICAgICAgICAgICAgICAgaWYgKHRoaXMubm9kZS5nZXRBdHRyaWJ1dGUoJ2FyaWEtZXhwYW5k ZWQnKSA9PT0gJ3RydWUnKSB7CiAgICAgICAgICAgICAgICAgICAgdGhpcy5ub2RlLnNldEF0dHJp YnV0ZSgnYXJpYS1leHBhbmRlZCcsICdmYWxzZScpOwogICAgICAgICAgICAgICAgfSBlbHNlIHsK ICAgICAgICAgICAgICAgICAgICB0aGlzLm5vZGUuc2V0QXR0cmlidXRlKCdhcmlhLWV4cGFuZGVk JywgJ3RydWUnKTsKICAgICAgICAgICAgICAgIH0KCiAgICAgICAgICAgICAgICB0aGlzLm5vZGUu Zm9jdXMoKTsKICAgICAgICAgICAgfQogICAgICAgIH0KICAgICAgICBjb25zdCBpbnRpYWxpc2Ug PSBmdW5jdGlvbigpIHsKICAgICAgICAgICAgYnV0dG9ucy5mb3JFYWNoKGVsID0+IHsKICAgICAg ICAgICAgICAgIG5ldyBBcmlhRXhwYW5kZWRJc3N1ZShlbCk7CiAgICAgICAgICAgIH0pCiAgICAg ICAgfQoKICAgICAgICB3aW5kb3cuYWRkRXZlbnRMaXN0ZW5lcignbG9hZCcsIGludGlhbGlzZSk7 CiAgICA8L3NjcmlwdD4KICAgIAo8L2JvZHk+CjwvaHRtbD4=
