Hi @volha-arkhipenka-sap,

I tested the <ui5-dialog> component directly using the Playground with header-text provided, and observed that VoiceOver does read the header, as long as the initial focus is placed on it. You can check the test example here.

According to the spec, the dialog header should be announced on focus, so the behavior depends on where the focus lands upon dialog open. In your example, the initial focus is set on the first item inside the dialog, not on the header, which likely explains why VoiceOver doesn’t announce it.

I’m going to proceed with closing this ticket for now. If any further questions arise or you need clarification, feel free to reopen it.

Best regards,
Nikola

Hi @NakataCode, thank you for the response.

However, when SelectDialog contains ListItemStandards, the focus is set on the first item automatically by SelectDialog. This focus behavoir seems to be default and internal for SelectDialog component when it has a list of ListItemStandards inside. The focus lands on the first ListItemStandard even in the example from the documentation https://sap.github.io/ui5-webcomponents-react/v2/?path=/docs/modals-popovers-selectdialog--docs.

Should it be considered as a bug of incorrect focus landing on SelectDialog open?

Hello @Lukas742,

It looks that this should be fixed in the Select Dialog, where slot "header" is used, but "accessibleName" is not provided.
See the documentation of the DIalog: https://sap.github.io/ui5-webcomponents/nightly/components/Dialog/#header

Best Regards,
Lidiya
