I have a custom post type
catalogues and there is a custom field
All catalogues are displaying right now, I have made a drop down of custom field brands and put it in an array and displaying it in a drop down… If I select LG from drop down, it should show all catalogues with LG. for example.
LG Washing Machine and if i select Symphony, it should
Symphony Catalogue 2015..
How can i achieve this in WordPress?
