What is best way to manage dropdown data from database?
1) create a table for each dropdown
or
2) 1 table for all dropdowns.
Also please consider relations between tables, for example Country, States and Cities.
And with consideration of scalability, like more dropdowns or more dropdown labels.

Hi vamsik0002 ,
I would suggest to create separate tables with foreign key relationships. And then you can use the selected option dropdown populate the following dropdown( cascading dropdowns ), pls refer the below link for https://docs.appian.com/suite/help/21.1/recipe-configure-cascading-dropdowns.html
Ex : Country is Parent table then State and then City table. For long Run its easy to maintain.
Country
CountryId_pk CountryName
1 Australia
2 USA
3 Singapore
State
stateid_pk StateName countryid_fk
1 Texas 2
2 California 2
3 Melbourne 1
Cityd_pk CityName Stateid_fk
1 Houston 1
2 Austin 1
3 Los Angeles 2
4 SanJose 2
Note: Also You can maintain single table. But above logic helps you refer/reuse wherever you need only fields.
Please let me know if this helps. Thanks
Hi Baratc,
Countries, states and cities is an example.
I am looking at a real time project with 10+ dropdowns, some with 10+ choices and some with 1-2 choices.
Maintaining 10+ tables with relations is cumbersome right, and there are dropdowns which depend on multiple fields.
Hi Vamsii,
i would suggest document all the possible combinations in excel and understand the relationship between values and take the decision.(need to do some matrix like combinations and add flags/boolean values). pls give a try and optimize to less tables(kind of rules table).
