Options for Html::tag with not only class/id

pwwl · January 28, 2018, 11:46pm

Here is the tag:

[html]<ul id="dn4" class="accordion" data-accordion data-allow-all-closed="true">[/html]

What is the best/elegant/smart way to set options array for Html::tag?

Especially for attribute with no value like "data-accordion"?

Hi pwwl, welcome to the forum.

Please look at the following page in API reference.

renderTagAttributes()

http://www.yiiframework.com/doc-2.0/yii-helpers-basehtml.html#renderTagAttributes()-detail

The "data" attribute is specially handled when it is receiving an array value. In this case, the array will be "expanded" and a list data attributes will be rendered.

For example, if
'data' => ['id' => 1, 'name' => 'yii']
then this will be rendered:
data-id="1" data-name="yii"

Try the following:




'data' => ['accordion', 'allow-all-closed' => true]

(Sorry, not tested)
