Merge sections
Sections can be merged together to cover your extension.
In this example we add another selector to the section on the products page section.
Starting section
Copied to your clipboard<section name="AdminProductsPageSection"><element name="addProductButton" type="button" selector="//button[@id='add_new_product-button']"/><element name="checkboxForProduct" type="button" selector="//*[contains(text(),'{{args}}')]/parent::td/preceding-sibling::td/label[@class='data-grid-checkbox-cell-inner']" parameterized="true"/><element name="actions" type="button" selector="//div[@class='col-xs-2']/div[@class='action-select-wrap']/button[@class='action-select']"/><element name="delete" type="button" selector="//*[contains(@class,'admin__data-grid-header-row row row-gutter')]//*[text()='Delete']"/><element name="ok" type="button" selector="//button[@data-role='action']//span[text()='OK']"/><element name="deletedSuccessMessage" type="button" selector="//*[@class='message message-success success']"/></section>
File to merge
Copied to your clipboard<section name="AdminProductsPageSection"><!-- myExtensionElement will simply be added to the page --><element name="myExtensionElement" type="button" selector="input.myExtension"/></section>
