    [
        'integrity' => 'sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T',

Tag objects usage

Tag classes allow working with tag as is object and then get a HTML code by method render() or type casting to string. For example, code:

echo \Yiisoft\Html\Tag\Div::tag()
    ->content(
        \Yiisoft\Html\Tag\A::tag()
            ->mailto('info@example.com')
            ->content('contact us')
            ->render()
    )
    ->encode(false)
    ->id('ContactEmail')
    ->class('red');

... will generate HTML:

<div id="ContactEmail" class="red"><a href="mailto:info@example.com">contact us</a></div>

Package has clasess for tags A, Button, Div, Img, Input (and specialized Checkbox, Radio), Label, Li, Link, Meta, Ol, Optgroup, Option, P, Script, Select, Span, Style, Textarea, Ul.

Generating custom tags

For generate custom tags, use the CustomTag class. For example, code:

echo \Yiisoft\Html\Tag\CustomTag::name('b')
    ->content('text')
    ->attribute('title', 'Important');

... will generate HTML:

<b title="Important">text</b>

HTML widgets usage

CheckboxList

echo \Yiisoft\Html\Widget\CheckboxList\CheckboxList::create('count')
	->items([1 => 'One', 2 => 'Two', 5 => 'Five'])
	->uncheckValue(0)
	->value(2, 5)
	->containerAttributes(['id' => 'main']);

Result will be:

<input type="hidden" name="count" value="0">
<div id="main">
<label><input type="checkbox" name="count[]" value="1"> One</label>
<label><input type="checkbox" name="count[]" value="2" checked> Two</label>
<label><input type="checkbox" name="count[]" value="5" checked> Five</label>
</div>

RadioList

echo \Yiisoft\Html\Widget\RadioList\RadioList::create('count')
    ->items([1 => 'One', 2 => 'Two', 5 => 'Five'])
    ->uncheckValue(0)
    ->value(2)
    ->containerAttributes(['id' => 'main'])
    ->render();

Result will be:

<input type="hidden" name="test" value="0">
<div id="main">
<label><input type="radio" name="test" value="1"> One</label>
<label><input type="radio" name="test" value="2" checked> Two</label>
<label><input type="radio" name="test" value="5"> Five</label>
</div>
