Not able to bind all data to accordion

Hi Webix team,

Why data is not binding in third accordion body?

Hello,
You can use something like next

$$("id_metadata_configuration_form")
  .queryView(a => {
      if (a.name == "accordion")
        a.getChildViews()[0].expand(); 
  })

queryView iterates through all sub-view, and expand opens the found panels
