<p>As the example above shows, the <code>&lt;fieldset&gt;</code> element provides a grouping for a part of an HTML form, with a nested {{htmlelement("legend")}} element providing a caption for the <code>&lt;fieldset&gt;</code>. It takes few attributes, the most notable of which are <code>form</code>, which can contain the <code>id</code> of a {{htmlelement("form")}} on the same page, allowing you to make the <code>&lt;fieldset&gt;</code> part of that <code>&lt;form&gt;</code> even if it is not nested inside it, and <code>disabled</code>, which allows you to disable the <code>&lt;fieldset&gt;</code> and all its contents in one go.</p>

<h2 id="Atributos">Atributos</h2>

<p>This element includes the <a href="/en-US/docs/HTML/Global_attributes">global attributes</a>.</p>

<dl>
 <dt>{{htmlattrdef("disabled")}} {{HTMLVersionInline(5)}}</dt>
 <dd>If this Boolean attribute is set, all form controls that are descendants of the <code>&lt;fieldset&gt;</code>, are disabled, meaning they are not editable but will be submitted along with <code>&lt;form&gt;</code> in comparison with {{htmlattrdef("disabled")}} attribute on form controls. They won't receive any browsing events, like mouse clicks or focus-related events. By default browsers display such controls grayed out. Note that form elements inside the {{HTMLElement("legend")}} element won't be disabled.</dd>
 <dt>{{htmlattrdef("form")}} {{HTMLVersionInline(5)}}</dt>
 <dd>This attribute takes the value of the <code>id</code> attribute of a {{HTMLElement("form")}} element you want the <code>&lt;fieldset&gt;</code> to be part of, even if it is not inside the form.</dd>
 <dt>{{htmlattrdef("name")}} {{HTMLVersionInline(5)}}</dt>
 <dd>The name associated with the group.
 <div class="note"><strong>Note</strong>: The caption for the fieldset is given by the first {{HTMLElement("legend")}} element nested inside it.</div>

<h2 id="Estilizar_com_CSS">Estilizar com CSS</h2>

<p>There are several special styling considerations for <code>&lt;fieldset&gt;</code>.</p>

<p>Its {{cssxref("display")}} value is <code>block</code> by default, and it establishes a block formatting context. If the <code>&lt;fieldset&gt;</code> is styled with an inline-level <code>display</code> value, it will behave as <code>inline-block</code>, otherwise it will behave as <code>block</code>. By default there is a 2px groove border surrounding the contents, and a small amount of default padding. The element has <code>min-inline-size: min-content</code> by default.</p>

<p>If a <code>&lt;legend&gt;</code> is present, it is placed over the block-start border. The <code>&lt;legend&gt;</code> shrink-wraps, and also establishes a formatting context. The <code>display</code> value is blockified (for example, <code>display: inline</code> behaves as <code>block</code>).</p>

<p>There will be an anonymous box holding the contents of the <code>&lt;fieldset&gt;</code>, which inherits certain properties from the <code>&lt;fieldset&gt;</code>. If the <code>&lt;fieldset&gt;</code> is styled with <code>display: grid</code> or <code>display: inline-grid</code>, then the anonymous box will be a grid formatting context. If the <code>&lt;fieldset&gt;</code> is styled with <code>display: flex</code> or <code>display: inline-flex</code>, then the anonymous box will be a flex formatting context. Otherwise it establishes a block formatting context.</p>

<p>You can feel free to style the <code>&lt;fieldset&gt;</code> and <code>&lt;legend&gt;</code> in any way you want to suit your page design.</p>

<div class="note">
<p><strong>Nota: </strong>as of this writing, there are bugs in Microsoft Edge and Google Chrome which prevent <a href="/en-US/docs/Glossary/Flexbox">flexbox</a> and <a href="/en-US/docs/Web/CSS/CSS_Grid_Layout">grid </a>layouts from being used inside a {{HTMLElement("fieldset")}}. <a href="https://github.com/w3c/csswg-drafts/issues/321">This GitHub issue</a> provides bug tracking links.</p>

<h2 id="Exemplo">Exemplo</h2>

<h3 id="Simple_fieldset">Simple fieldset</h3>

<p>This example shows a really simple <code>&lt;fieldset&gt;</code> example, with a <code>&lt;legend&gt;</code>, and a single control inside it.</p>

<pre class="brush: html">&lt;form action="#"&gt;
  &lt;fieldset&gt;
    &lt;legend&gt;Simple fieldset&lt;/legend&gt;
    &lt;input type="radio" id="radio"&gt;
    &lt;label for="radio"&gt;Spirit of radio&lt;/label&gt;
  &lt;/fieldset&gt;
&lt;/form&gt;</pre>

<p>{{ EmbedLiveSample('Simple_fieldset', '100%', '80') }}</p>

<h3 id="fieldset_desativado">"fieldset" desativado</h3>

<p>This example shows a disabled <code>&lt;fieldset&gt;</code> with two controls inside it. Note how both the controls are disabled due to being inside a disabled <code>&lt;fieldset&gt;</code>.</p>

<pre class="brush: html">&lt;form action="#"&gt;
  &lt;fieldset disabled&gt;
    &lt;legend&gt;Disabled fieldset&lt;/legend&gt;
    &lt;div&gt;
      &lt;label for="name"&gt;Name: &lt;/label&gt;
      &lt;input type="text" id="name" value="Chris"&gt;
    &lt;/div&gt;
    &lt;div&gt;
      &lt;label for="pwd"&gt;Archetype: &lt;/label&gt;
      &lt;input type="password" id="pwd" value="Wookie"&gt;
    &lt;/div&gt;
  &lt;/fieldset&gt;
&lt;/form&gt;</pre>
