Unable to expand filters in the Filter widget in Web AppBuilder for ArcGIS when the 'Group filters by layer' box is checked and the input type for the expression in the filter is set to Value.

Workaround

• In the Configure Filter interface, uncheck the box next to 'Group filters by layer'. When this box is unchecked, all the filters expand and are visible.
• Instead of selecting Value for the input value for an expression, select Unique. If the input value is set to Unique, the filter can be expanded. This is functional even when the box next to 'Group filters by layer' is checked.
• Create one filter with multiple expressions instead on having multiple filters with only one expression each.
