Espo.define('crm:views/account/detail', 'views/detail', function (Dep) {

return Dep.extend({

setup: function () {
Dep.prototype.setup.call(this);
this.menu.buttons.push({
'label': 'Test',
'style' : 'default',
'link': 'https://ya.ru',
'iconHtml': '<span class="glyphicon glyphicon-th-list"></span>'
});
},
relatedAttributeMap: {
'contacts': {
'billingAddressCity': 'addressCity',
