![]() Expandable sectionsĮxpandable sections, also known as disclosures, contain content that is hidden until the user presses a button. The AutoHeight property can be used to automatically adjust the control's size when it is inside a Form, Scrollable screen, or Gallery. Ensure the Label is large enough to fit text. ![]() Don't making labels scrollable if they're not meant to be buttons. However, it will also turn them into buttons. Keyboard users can't scroll Forms, Scrollable screens, and Containers if there are no interactive controls inside them.įor Galleries with no interactive content, you can set TabIndex on the Gallery itself so that keyboard users can focus on it and use arrow keys to scroll it.įor Labels, setting TabIndex will make them focusable for keyboard scrolling. Create a code component that implements an accessible combo box.Use the built-in Combo box or Drop down.Combo boxes must handle arrow keys and set appropriate roles and states on its components. However, combo boxes assembled from built-in controls are not accessible. It is possible to emulate a combo box by combining a Text Input and a Gallery. Create a code component that implements an accessible table.Present data in one direction only with a Gallery.Rows and columns have to be annotated so that screen reader users can understand their structure and navigate cells. Avoid using Galleries to present data in rows and columns. The only built-in control that supports two-dimensional data is the Data Table. Create a code component that implements an accessible tabbed interface.For example, if an Icon is used as a tab, its label could be “Documents. Append the role and state of a tab to its AccessibleLabel. Put each tab panel on a separate screen.Appropriate control roles and states are required. The list of tabs should be navigable with arrow keys. A tabbed interface is made up of a list of tabs and a panel that shows content associated with the selected tab. Create a code component that implements an accessible dialog.Use separate screens for each “dialog”.These overlays require focus management, hiding background content from screen readers, and appropriate control roles. Dialogs and overlaysĭialogs and user interfaces that appear on top of other content are not supported. In this article, you'll learn about these accessibility limitations in canvas apps, and how can you improve the app interface to make it more accessible. Sometimes, the combination of app design, use of various controls, and the configured control properties may result in an app to have an inaccessible user interface. You can design and build accessible canvas apps with built-in controls.
