Make Field Required Based Off Value of Another Field

Question

[we are on the cloud version]

I see several older posts talking about plugins and such. Is there any update to make this a built in function of Jira?

If Field One is checked,

Field 2,3,5 are required.

I believe that JIRA doesn't have built in condition-based post function. See JRACLOUD-36316.

So, the best way would be achieving this via add-ons/plugins.
