3. You will see several major problems with accessibility;
4. Comboboxes (for language, for protocols, etc) are not accessible with keyboard and are not exposed to a screenreader. Consider using native elements rather than something custom; You will see that menu options have some "icon:something" text near every option and this is annoying to listen when you navigate with screenreader; You may notice that some icons have no text description at all and are identified only by an icon which is announced like "graphics" or "icon I"; Expected behavior The web panel interface should be usable with a screenreader and should conform to WCAG standard; Screenshots n/a Desktop (please complete the following information): OS: Windows Browser: Brave, Chrome, Edge Version: Latest at versions at the moment of creation of this issue Smartphone (please complete the following information): n/a Additional context NVDA screenreader version 2024.1 is used
