Thanks for the prompt reply. I made following changes, it's now showing Any in the search box, it makes more sense than ask user to select something.

casaroyal/template-parts/real-estate/search-form.php (for left search panel)

Delete Select Location/Select Status/Select Type from line 207, 225, 243. 

casaroyal-plugin/shortcodes/td-shortcode-properties-asf.php (For homepage top search bar)

Delete Select Location/Select Status/Select Type from line 138, 147, 156

Delete Select Location/Select Status/Select Type from line 196, 204, 212

casaroyal/template-parts/real-estate/search-form-full-width.php (probably not required) 

Delete Select Location/Select Status/Select Type from line 127, 143, 159

casaroyal-plugin/shortcodes/td-shortcode-properties-map.php (probably not required) 

Delete Select Location/Select Status/Select Type from line 108, 117, 126

Hey,

The "Select Type" option you ca find in

casaroyal-plugin/shortcodes/td-shortcode-properties-asf.php: line 138 and 196

casaroyal-plugin/shortcodes/td-shortcode-properties-map.php: line 108

casaroyal/template-parts/real-estate/search-form-full-width.php: line 72

casaroyal/template-parts/real-estate/search-form.php: line 122

when I click 'Type' in the search box, in the expended list there is a useless option 'select type' on the top, similar issue with the 'Status' search box. How do I remove this redundant option from the list?
