Copy Button
<wa-copy-button>
Copy buttons copy text to the clipboard when the user activates them. They provide built-in success and error feedback so users know the copy worked.
Copy buttons use the browser's clipboard.writeText() method, which requires a secure context (HTTPS) in most browsers.
Examples
Custom Labels
The default copy button shows a tooltip on hover and focus, and the tooltip text changes briefly to confirm a successful or failed copy. You can customize these labels using the copy-label, success-label, and error-label attributes. The copy-label is also used as the button's accessible name.
Custom Icons
Use the copy-icon, success-icon, and error-icon slots to customize the icons that get displayed for each state. You can use <wa-icon> or your own images.
Custom Trigger
By default, the copy button renders an icon-only button. You can slot in any element to use as a custom trigger instead. This works with Web Awesome buttons, native buttons, or any clickable element.
You can also use a native button as the trigger.
Custom triggers automatically receive the same tooltip and copy feedback as the default trigger — no extra wiring required. The icon swap is the only piece that's specific to the default trigger. Use without-tooltip to opt out of the tooltip, and use the wa-copy and wa-error events or the :state(success) and :state(error) CSS custom states for additional feedback.
Copying Values From Other Elements
Normally, the data that gets copied will come from the component's value attribute, but you can copy data from any element within the same document by providing its id to the from attribute.
When using the from attribute, the element's textContent will be copied by default. Passing an attribute or property modifier will let you copy data from one of the element's attributes or properties instead.
To copy data from an attribute, use from="id[attr]" where id is the id of the target element and attr is the name of the attribute you'd like to copy. To copy data from a property, use from="id.prop" where id is the id of the target element and prop is the name of the property you'd like to copy.
Handling Errors
A copy error will occur if the value is an empty string, if the from attribute points to an id that doesn't exist, or if the browser rejects the operation for any reason. When this happens, the wa-error event will be emitted.
This example demonstrates what happens when a copy error occurs. You can customize the error label and icon using the error-label attribute and the error-icon slot, respectively.
Disabled
Copy buttons can be disabled by adding the disabled attribute.
Changing Feedback Duration
After copying, the tooltip briefly displays a success or error label. Use the feedback-duration attribute to control how long it stays visible.
Tooltip Modes
The tooltip attribute controls when the built-in tooltip appears. It applies to both the default trigger and custom triggers.
full(default): the tooltip shows on hover and focus, and is reused to display copy feedback.copy: the tooltip stays silent on hover and focus, and only appears briefly to confirm a successful or failed copy.none: no tooltip is shown in any state.
Changing Tooltip Placement
The tooltip is shown above the trigger by default. Use the tooltip-placement attribute to position it on the top, right, bottom, or left.
The same attribute applies to custom triggers.
Custom Styles
You can customize the button to your liking with CSS.
