Default Toggle for Svelte

The Toggle is uncontrolled by default: it stores its own pressed state, flips it on a click or on Space and Enter, and exposes it as aria-pressed. It starts unpressed. Pass defaultPressed to start it pressed.

An icon has no text, so without a label a screen reader announces only "toggle button, not pressed". aria-label="Toggle bold" gives the button its name, and the icon is marked aria-hidden="true" so it isn't read as well. When the label is visible, as in the Toggle with Text example, the text names the button and no aria-label is needed.

A Toggle is a button that stays pressed, like Bold in an editor toolbar, and is announced as a pressed button. A Switch turns a setting on or off, like notifications or dark mode, and is announced as a switch. Use the Toggle when the button is the state of the thing you're working on, and the Switch for a preference that applies elsewhere.

Yes. Every Toggle sets aria-pressed while it's on, so style that attribute: for example aria-pressed:bg-primary aria-pressed:text-primary-foreground on the Toggle. To change every Toggle in your app, edit the Toggle in your ui folder instead of repeating the classes.

Keep the pressed state in your own state and pass it back to the Toggle, when other parts of the page need to read or set it. Pass pressed; onPressedChange receives the new boolean.

Use the Toggle Group: wrap a ToggleGroupItem for each option in a ToggleGroup, which tracks which items are pressed and makes the row one Tab stop with arrow-key navigation. One item is pressed at a time by default; add multiple to let several be pressed together.
