How to expand the "Buyer" block in sale.order.ajax after selecting "Payer Type"?

Question

1C-Bitrix

Now when loading the checkout page (sale.order.ajax / D7), I have all the blocks open. But as soon as the "Payer Type" is changed, the "Buyer" block collapses, how to open the block after selecting the "Payer Type"

Answer 1

sale.order.ajax: expand all blocks.
.default template sale.order.ajax.
1. Activate editing of "Region" and "User" blocks:
Comment lines from 1694 to 1698

/*if (this.activeSectionId !== this.regionBlockNode.id)
  this.editFadeRegionContent(this.regionBlockNode.querySelector('.bx-soa-section-content'));

if (this.activeSectionId != this.propsBlockNode.id)
  this.editFadePropsContent(this.propsBlockNode.querySelector('.bx-soa-section-content'));*/

2. Remove the "Back" and "Next" buttons:
Comment lines from 2224 to 2234

/*node.appendChild(
  BX.create('DIV', {
    props: {className: 'row bx-soa-more'},
    children: [
      BX.create('DIV', {
        props: {className: 'bx-soa-more-btn col-xs-12'},
        children: buttons
      })
    ]
  })
);*/

3. Expand all blocks:
Change line 2461 from to line 4. Remove actions when clicking on headings: Comment lines from 2465 to 2478

/*BX.unbindAll(titleNode);
if (this.result.SHOW_AUTH)
{
  BX.bind(titleNode, 'click', BX.delegate(function(){
    this.animateScrollTo(this.authBlockNode);
    this.addAnimationEffect(this.authBlockNode, 'bx-step-good');
  }, this));
}
else
{
  BX.bind(titleNode, 'click', BX.proxy(this.showByClick, this));
  editButton = titleNode.querySelector('.bx-soa-editstep');
  editButton && BX.bind(editButton, 'click', BX.proxy(this.showByClick, this));
}*/

5. Remove the "Edit" links:
Add the following code to the end of the editOrder function on line 2404

var editSteps = this.orderBlockNode.querySelectorAll('.bx-soa-editstep'), i;
for (i in editSteps) {
  if (editSteps.hasOwnProperty(i)) {
    BX.remove(editSteps[i]);
    }
  }
