Is this feature removed from yii2 or what ?

In yii 1 version there was a CHtml::link method

Where in option you can set the post params.

eg CHtml::link("Link", "#", array(

"submit"=>"someAction",

"params"=>array("somePostVar"=>"postValue"),

))

But in yii2 I cant get the Html::a("Link", "#", [

"data"=>[

'method' => 'post',


"params"=>array("somePostVar"=>"postValue"),

]

]

Is this feature removed from yii2 or what ??????
