Permitted content | Phrasing content or one element of Heading content |
---|---|

Permitted ARIA roles | {{ARIARole("button")}} |
DOM interface | {{domxref("HTMLElement")}} |
This element only includes the global attributes.
The <summary>
element's contents can be any heading content, plain text, or HTML that can be used within a paragraph.
A <summary>
element may only be used as the first child of a <details>
element. When the user clicks on the summary, the parent <details>
element is toggled open or closed, and then a {{event("toggle")}} event is sent to the <details>
element, which can be used to let you know when this state change occurs.
If a <details>
element's first child is not a <summary>
element, the {{Glossary("user agent")}} will use a default string (typically "Details") as the label for the disclosure box.
Per the HTML specification, the default style for <summary>
elements includes display: list-item
. This makes it possible to change or remove the icon displayed as the disclosure widget next to the label from the default, which is typically a triangle.
You can also change the style to display: block
to remove the disclosure triangle.
See the {{anch("Browser compatibility")}} section for details, as not all browsers support full functionality of this element yet.
Below are some examples showing <summary>
in use. You can find more examples in the documentation for the {{HTMLElement("details")}} element.
A simple example showing the use of <summary>
in a {{HTMLElement("details")}} element:
<details open> <summary>Overview</summary> <ol> <li>Cash on hand: $500.00</li> <li>Current invoice: $75.30</li> <li>Due date: 5/6/19</li> </ol> </details>
{{EmbedLiveSample("Basic_example", 650, 120)}}
You can use heading elements in <summary>
, like this:
<details open> <summary><h4>Overview</h4></summary> <ol> <li>Cash on hand: $500.00</li> <li>Current invoice: $75.30</li> <li>Due date: 5/6/19</li> </ol> </details>
{{EmbedLiveSample("Summaries_as_headings", 650, 120)}}
This currently has some spacing issues that could be addressed using CSS.
This example adds some semantics to the <summary>
element to indicate the label as important:
<details open> <summary><strong>Overview</strong></summary> <ol> <li>Cash on hand: $500.00</li> <li>Current invoice: $75.30</li> <li>Due date: 5/6/19</li> </ol> </details>
{{EmbedLiveSample("HTML_in_summaries", 650, 120)}}
