Is there any way for triple cascading option or multi level Cascading Options ?

Question

We are trying to Implement some Multi-level Cascading options and trying to achieve it. 
Tried some Plugin, it was working in Internal Create Option, But for Portal, it is not working as expected. So any way for achieving that part or can we expect something like that in future

@Santhosh Raj - Custom fields only allow 2 levels (A->B), and the new feature on the roadmap is bringing that configuration to Forms.

There is no way to have a 3-level cascading field. When the 2-level ones come into Forms you can condense the above slightly:

Cascading Select List 1

--- Section: Conditional: Select List 1 = Option 1 - Option A ---

Select List 1a

But whether can we have it in Jira Custom fields and add those fields in Request form and that would reflect in portal ?
Is that the feature going to come or is it JSM forms.
Also will it have multi-level cascading fields like A --> B --> C levels @Jovin

Hey @Santhosh Raj

Currently the forms that can be displayed on the Portal do not allow cascading fields. That is, however, a feature on the Roadmap: https://www.atlassian.com/wac/roadmap/cloud/cascading-fields-in-forms?selectedProduct=&search=casc&p=96ced183-30

For the time being a workaround solution would be to have a series of Single Selects that have conditional sections that are only displayed when a certain value is added.

e.g.

Select List 1

--- Section: Conditional: Select List 1 = Option 1 ---

Select List 1a

--- Section: Conditional: Select List 1a = Option 1 ---

Select List 1a.1

--- Section: Conditional: Select List 1 = Option 2 ---

Select List 1b

--- Section: Conditional: Select List 1b = Option 1 ---

Select List 1b.1

etc.
