Hi @soumiya

You could achieve that by manipulating the selector and making it more "generic".

First you have to inspect the selector extracted from multiple instances of the web page and determine what remains the same in every instance. Then, you can edit the CSS selector and modify the operator of the attribute that changes accordingly:

Also, you could add an additional "fallback" selector by separating the two CSS selectors by a comma.

I hope the above helps!

Hello @soumiya,

Since the class remains constant, you would need to customize the selector to only look for the class attribute value and deselect the remaining attributes (name, ordinal, innerText , etc.) to enable PAD to find the element consistently.

Please follow the steps below to edit a selector:
Search for the element that needs to be edited in the UI elements pane.

Right click on the element and go to edit selectors.

Hover over the selector captured and right click on it to open the selector builder to edit it.

This will open up the selector builder which can be used to easily customize the selector as appropriate. In your case you would need to only select the class attribute because it remains constant and deselect the ordinal and InnerText attributes as they are dynamic.

Further, if the above does not resolve your issue, please send us the selector path of the target element and the URL where it exists so that we can provide a solution.

Thank you for trying Power Automate Desktop.

Hello @soumiya,

RPA challenge website is dynamic in a way that it moves the field elements every time it is loaded. But, the important to note there is that the other div of the element always contains consistent field labels ("Address", "First Name", "Company name", etc.). To target the correct element each time please customize the selector (as mentioned before) so that it looks for the field names and then the input field to populate it - for example like below:
For Address:

First name selector: div:contains("First Name") > input
Similarly you can change the text inside contains operator to find any input field names you want. (Role in Company, Last Name, Company Name, Email, Phone Number, etc)
Hope it helps.
