I am running WAB Developer on Portal.
I have a large table that I want to include in the Attribute Table which is filtered to map extent. Requerying this table on every pan or zoom is a big performance hit. By default the Attribute Table is collapsed and I would like for it to stay inactive until expanded to prevent the excessive load and then to go inactive again when collapsed.
This way the tables would all be unpopulated until the tab is expanded and then would behave normally. Then when collapsed would cease populating again.
