Title: Dynamic array based on Input from Parent field Last modified: December 2, 2024 --- # Dynamic array based on Input from Parent field * Resolved [mionigba](https://wordpress.org/support/users/mionigba/) * (@mionigba) * [1 year, 6 months ago](https://wordpress.org/support/topic/dynamic-array-based-on-input-from-parent-field/) * Hello Sir, There’s a Logic I need to implement in my Project, but I don’t know if I will be able to implement it with **AR Member** Registration Form!**THE LOGIC**There are **36** States, and each State has **multiple Local Governments**. Each Local Government has **multiple Wards**.And each Ward has **multiple Polling Units**.For clarity, I will use 3 States as example:1.) **STATE**: Lagos || ** LOCAL GOVERNMENTS**: 20 || **WARDS**: 8 wards || **POLLING UNITS**: 162.) **STATE**: Kaduna || **LOCAL GOVERNMENTS**: 15 || **WARDS**: 12 wards || **POLLING UNITS**: 243.) **STATE**: Ondo || **LOCAL GOVERNMENTS**: 16 || **WARDS**: 10 wards || ** POLLING UNITS**: 18**THE LOGIC****State**, **Local Government**, **Ward** and** Polling Unit** are all **Dropdown Fields**.If the user selects a **State**, the _Local Government_, _Ward_ and _Polling Unit_ fields should only allow selection of content limited to the chosen State.So that, if I select **Lagos** as my State, I should have option to select only one Local Government from the list of Local Governments that are only in Lagos, and should only be able to select one from the list of Wards that are only in the Local Government that I have chosen, which is in Lagos.When I have chosen that Ward that is within a Local Government, that is in Lagos State, I should be able to select only Polling Units within that Ward.But if I select **Kaduna** as my State, I should have option to select only one Local Government from the list of Local Governments that are only in Kaduna, and should only be able to select one **Ward** from the list of Wards that are only in the Local Government that I have chosen, which is in Kaduna.When I have chosen that Ward that is within a Local Government, that is in Kaduna State, I should be able to select only one Polling Unit within that Ward.In essence, the value that can be selected in **Local Government**, **Ward** and **Polling Unit** fields are dynamically populated according to the **State** chosen.As an example from this website ( [https://pre.cac.gov.ng](https://pre.cac.gov.ng)), you will see that when I select **Lagos** as **State** here — [https://prnt.sc/YFVdxltorzE5](https://prnt.sc/YFVdxltorzE5) Or **Kaduna** as **State** here — [https://prnt.sc/Z2ymzonOq8uQ](https://prnt.sc/Z2ymzonOq8uQ) You will see that the **LGA** or **Local Government Area** information changes. THE PROBLEMI don’t know if I will be able to implement this Logic with **AR Member Registration Form**!Needing to hear from you soon.Regards.
