While customizing a selector what all elements should I try to keep for avoiding failure and what all elements should I remove
Try to add AANAME ,TITLE,ID attribute and if you found any dates or dynamic content replace it with * wild card.
Just note down the selectors of the same element in an text file by doing multiple page refresh. Comparing the selectors of the element you will get idea about the attributes which is changing for every refresh.
Avoid using attributes like CtrlID, row ,col ,isleaf or you can you these attributes if the selector doesn’t changes even after multiple refresh.
you can use all the properties mentioned in Properties Explorer and/or Properties for Selector Editor
How can I use the properties?
type in the property and value in the sector editor window. (selected in blue in above)
