Limitations of the select element
Why does the select element (aka drop down menu) not show up on the agent side when opened on the customer side?
The select element is rendered natively by the operating system. The list that appears when clicking on the element is not represented in the DOM tree (Document Object Model). It can therefore not be recognized by unblu. On the following image, the selection is in progress on the left at the customer, but the agent does not see it.
After selecting an option, the result is captured and shown to the agent as shown in the image below.
