TabView used have a variable 'activeIndex' but I get the message can't bind to activeIndex as it's not a member of tabView.

Many components are working well but I'm stuck on how to set the active tab in TypeScript code. Node (for AoT issues): node -version = 8.9.I've just begun using PrimeNG with an Angular2 TypeScript project. Accessibility needs to be considered before building any component, so addressing these issues accounts for people with disabilities to have equal access to the components. People with motor impairments and users with vision impairments will currently have barriers to properly interact with the component. Inclusion and equal access needs to be provided for all components. What is the motivation / use case for changing the behavior? Navigate through the tablist using keyboard interactions (Tab, Shift + Tab) and make sure only interactive elements receive keyboard focus.With respect to keyboard, TAB for the first time moves focus to the selected tab and the second time TAB is activated, focus moves to the tabpanel (provide tabindex="0") for the active tab.
ng2- charts provide line chart, pie chart, bar chart, doughnut chart, radar chart, polar area chat, bubble chart and scatter chart >. The tabindex="0" should be set on the container which has the role="tab". If you want to add chart in your angular 12 project then we will suggest you to use ng2- charts npm package to adding chart.This way when screen reader navigates to the page, valid information is communicated to screen readers. After that using JavaScript, the value of the aria-selected needs to be toggled to either false on true based on the interaction. Initially, for all the tabs other than the one selected, the aria-selected value needs to be present in the DOM and value needs to be set to false.Please follow the "Keyboard Support" in this link: or " (Internal%20Content)/demo.htm" I have stumble along and have not come up with a. I am trying to conserve space on a page that is full, and have a Calendar control that I would like to be accessible from multiple tabs, so I am trying to place the Calendar control on the same row as the tabs for the p-tabView control. The keyboard paradigm for the tab structure can be found in the following link. PrimeNG, p-tabView placing extra content on tab line.Focus must be set on the link inside of the list item. The role="tab" is set on the links, so when focus moves the tab related ARIA role is not exposed to Screen readers. ) which will not communicate the necessary information.Tabindex attribute is set on the wrong element (.Dynamically adding the aria-selected attribute using JavaScript causes unexpected rendering of information to screen readers. Only when the links are activated, the aria-selected is set dynamically. When the page is rendered, for all the tabs other than the one that is selected, the aria-selected attribute is not present. The default value for aria-selected as per specifications is undefined.First time activating the tab key moves focus into the tablist and then into the tabpanel that is active.
Tab keys must not be used to move around the tabs. Arrow keys (Left, Right) arrow must move through the tabs. The arrow keys needs to move between the link in the tablist and tab key takes the user to the tabpanel that is currently active.
