Title: Conditional or Step Filter Last modified: April 14, 2023 --- # Conditional or Step Filter * Resolved [den1sa](https://wordpress.org/support/users/den1sa/) * (@den1sa) * [3 years ago](https://wordpress.org/support/topic/conditional-or-step-filter/) * Hi, * In Ultimate Member i have the ability to filter the contents of the memberships. However, what i need to do is create a conditional filter. For example… * If I have a list of vehicle types in one dropdown filter, e.g. * **VEHICLE TYPES FIELD** CarsVansLorrysAeroplanesHelicopters * When the user selects one of the items, lets say ‘Cars’, a new dropdown box appears with a list of cars, e.g. * **CAR TYPES FIELD** HatchbackSUVSaloon * I already have separate fields for each vehicle type, all i need Ultimate Member filter to do is show the Car Types field when Cars is selected from the Vehicle Type dropdown field. Or to show the Helicopter Types dropdown field when Helicopters is selected from the Vehicle Types dropdown field, and so on. * So it like having the ability to show/hide fields in the filter based on a previous selection in this case from the Vehicle Types Field. So if Cars is selected, only the Car Types field is shown and the Helicopter Types, Van Types, etc, are hidden. * **Vehicle Types Field**—-**Sub-Type Field** Car———————-(Car Types) Hatchback, SUV, Saloon…Helicopter—————(Helicopter Types) Compound, Tandem Rotor…Vans——————–( Van Types) Box Van, City Van, Crew Van,… * Any help will be greatly appreciated. * Denis - This topic was modified 3 years ago by [den1sa](https://wordpress.org/support/users/den1sa/).

Now when you select Car from the Vehicle List, the Vehicle Type list the car types. This also now works in the filter list. * Thank you MissVeronica for this solution, however, due to the structure of my data, rather than having one field that contains all the vehicle types, I have a separate field per vehicle type. So, one that contains all Car Types, another that contains all Van types, and so on… * So my question is how do I hide all the Vehicle Type fields and only show the correct Vehicle Type field (e.g. Car Types or Van Types, etc) based on the selection in the Vehicle List? * Thread Starter [den1sa](https://wordpress.org/support/users/den1sa/) * (@den1sa) * [3 years ago](https://wordpress.org/support/topic/conditional-or-step-filter/#post-16657793) * Hi MissVeronica, * Thank you.
