Thank you for clarification. You're right, this is how it works in Jira.

You can try to use Forms. But it's necessary to split your second custom field (with Cx) to two. So you will be able to create the first section with first custom field - category Px. Depending on selection, you will present different custom field: one with C1, C2 or second with C3, C4. But it's difficult to scale.

Another option which I can propose is using our app Multilevel Select for Jira which allows you to create multistructure. In the configuration, you can define that all levels must be selected (not only the first one).

Hi @Kate Pawlak _Appsvio_ ,

Thanks for quick response.

Cascading custom field is good choice but issue is when we make that field as required then without selecting sub category choice (C1,C2...) we can able to submit form.
so, I want both should be required  in single Cascading custom field then only we have to submit form.
For that do we have any solution....

Thanks

Hi @veerabhaskar,

If you have a such simple structure, would you consider using cascading custom field? It allows you to create a two level cascading structure.

P1

-->C1

-->C2

P2

-->C3

-->C4
