Add Custom Attributes to Elements
Right-click on the edit button of the element and click Edit section to open the section’s settings panel. Likewise, if editing a Widget, right-clicking will show the option to Edit Widget, and editing a Column will show Edit Column.
Go to Advanced > Custom Attributes
Add your code for the element to the editor, using the format key|value . For example, to add role="presentation" to the element's HTML, enter role|presentation here.
Set custom attributes for the wrapper element, with each attribute in a separate line. Separate attribute key from the value using the | character.
