How to change form error validation type in yii2?

Question

Yii

Hello. I use ActiveForm and faced the following problem: if the inputs are arranged horizontally, then the help-block block, in which errors are displayed, breaks the entire layout.

pos: absolute won't solve the problem, because the bottom blocks don't recede lower (which is not surprising), and the error text runs over the text of the next input in the list
Questions are:
1) How can I solve this problem without changing the horizontal position of the inputs?
2) In what file is a line like $('.help-block').text(error)? Searched, did not find. It would be possible to add .addClass('block'), and make it popup
3) How to display the error message in another place? In a corner, for example

Answer 1

Goodnight.
Use errorSummary
<?= $form->errorSummary($model) ?>
