While it's possible to filter the list, it is currently not possible to browse the full list like it is in the current select control.` the panel search bar is very robust which supports key word search column & metric names, label/verbose name search, description, warning, information. when # of column reach 50, i doubt scrolling through the list is the primary way to look for drop objects. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
