Button
- To clean the filter we need a button. Let’s get one from the plus in the toolbar

- Put the button near the Year dropdown and rename it

- Go to the Button_Clean_Filters - onClick

- Put the following code
// Remove all filters from the model
Table_Games_Sales.getDataSource().removeDimensionFilter("Name");
Table_Games_Sales.getDataSource().removeDimensionFilter("Publisher");
Table_Games_Sales.getDataSource().removeDimensionFilter("Year");
//Set all dropdowns selection to empty
Dropdown_Name.setSelectedKey('');
Dropdown_Publisher.setSelectedKey('');
Dropdown_Year.setSelectedKey('');

- Button should now work properly
