Copy Button

A button that copies the attached or associated text upon interaction.


When to use

  • To copy plain text, large code snippets, and input values.
  • When needing separation between the text-to-copy and the copy interaction.

When not to use

  • To copy short code snippets, such as URLs, tokens, IDs, use a Copy Snippet.


The Copy Button comes in small and medium sizes. Use the size that best fits the hierarchy of the UI.


Place the Copy Button as close to the content being copied as possible. Avoid too much visual separation between the content and the button to ensure users understand what will be copied to the clipboard.


Placing the Copy Button far away from the content being copied may make it challenging for users to recognize what they are copying to their clipboard.

Example of the Copy Button component using improper placement


Placing a Copy Button close to the content explicitly communicates what is being copied.

How to use this component

The basic invocation requires text and targetToCopy to be passed:

The button will copy the text in this paragraph element.

<p id="clipboardTarget">
  The button will copy the text in this paragraph element.
<Hds::Copy::Button @text="Copy" @targetToCopy="#clipboardTarget" />


The button will copy the text in this paragraph element.

<p id="clipboardTarget2">
  The button will copy the text in this paragraph element.
<Hds::Copy::Button @text="Copy" @isIconOnly={{true}} @targetToCopy="#clipboardTarget2" />


The component supports small and medium sizes (medium is the default):

The button will copy the text in this paragraph element.

<p id="clipboardTarget3">
  The button will copy the text in this paragraph element.
<Hds::Copy::Button @text="Copy" @size="small" @targetToCopy="#clipboardTarget3" />


This indicates that the component should take up the full-width of the parent container. It’s set to false by default.

The button will copy the text in this paragraph element.

<p id="clipboardTarget4">
  The button will copy the text in this paragraph element.
<Hds::Copy::Button @text="Copy" @targetToCopy="#clipboardTarget4" @isFullWidth={{true}} />

Text to Copy

The consumer can also indicate a string to be copied instead of indicating a target element:

<Hds::Copy::Button @text="Copy your secret key" @textToCopy="someSecretThingGoesHere" />
