HTML <fieldset> Tag
<fieldset> tag represents a group of form elements in an HTML document.
<fieldset> tag can be used with the
<legend> tag to make a form more readable and/or easier to comprehend.
<fieldset> tag is written as
</fieldset> with the grouped form controls inserted between the start and end tags.
You can use the
disabled attribute to disable all child form controls within the
<fieldset> element. You can also use the
form attribute to associate the element with a
<form> element on the same document.
Basic tag usage
Here we create two groups of form elements - one for name details, the other for gender.
Add a Legend
You can use the
<legend> element to provide a legend for the
<fieldset> elements. This makes it easier for users to understand what each
<fieldset> element represents.
You can disable all elements within a
<fieldset> element by using the
disabled attribute. This prevents users from being able to interact with the form controls.
disabled attribute is a boolean attribute (its value is either
false). The mere presence of this attribute sets its value to
true. Therefore, you don't need to add a value (simply writing
disabled is all that is required to disable the element).
Here, we disable the first
<fieldset> element ("Name Details").
You can add styles to the
<fieldset> element, just as you can with any other element.
Attributes can be added to an HTML element to provide more information about how the element should appear or behave.
There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.
<fieldset> element accepts the following attributes.
This table shows the attributes that are specific to the
|disabled||Disables all form control descendants of the
This is a boolean attribute. If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace (i.e. either
|form||Specifies a form to associate this
|name||Specifies the name of the
The following attributes are standard across all HTML5 elements. Therefore, you can use these attributes with the
<fieldset> tag , as well as with all other HTML tags.
For a full explanation of these attributes, see HTML 5 global attributes.
Event Handler Content Attributes
Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain "event" occurs. Each event handler content attribute deals with a different event.
Below are the standard HTML5 event handler content attributes.
Again, you can use any of these with the
<fieldset> element, as well as any other HTML5 element.
For a full explanation of these attributes, see HTML 5 event handler content attributes.
Differences Between HTML 4 & HTML 5
HTML5 has added 3 new attributes for the
<fieldset> element. These are:
align attribute is obsolete in HTML5 (it was already deprecated in HTML 4).
Here's a template for the
<fieldset> tag with all available attributes for the tag (based on HTML5). These are grouped into attribute types, each type separated by a space. In many cases, you will probably only need one or two (if any) attributes. Simply remove the attributes you don't need.
Here are the official specifications for the
- HTML5 Specification (W3C)
- HTML Living Standard (WHATWG)
- Current W3C Draft (the next version that is currently being worked on)
- HTML 4 (W3C)
What's the Difference?
W3C creates "snapshot" specifications that don't change once defined. So the HTML5 specification won't change once it becomes an official recommendation. WHATWG on the other hand, develops a "living standard" that is updated on a regular basis. In general, you will probably find that the HTML living standard will be more closely aligned to the current W3C draft than to the HTML5 specification.
