How to create a filter for Real Estate website?

Take a look at the post Let users filter data in a table for a discussion regarding more complex filters.

You can use multiple dropdowns in a filter like this:

export function filterButton_onClick() {
	$w("#dataset1").setFilter(wixData.filter() 
                .contains("type", $w("#selection1").value) 
                .contains("title", $w("#selection2").value)
        );    
   })

In the above example, #selection1 and #selection2 are the two dropdown menus. Together they will filter the query.

Look at the wix-data.filter API for more information.

Good luck,
