Looks like this question fall under my radar, sorry about that, Manish et al,
Let me provide a bit of an extended explanation here. Dynamic rows in a structure are those created by the Automation. Automation is a set of rules and within these rules, you can only move issues that comply with these rules. So you can put a story, task, etc under Epic, provided you have Stories under Epic extender in your structure, but you won't be able to put an epic under epic this way. Though Linked issues extender will allow any type of hierarchy if needed.
Now, generators are something you can never put under a dynamic row, as these are not issues and cannot have links themselves. Ditto folders. Ditto memos.
However, people often need to adjust their dynamic structures in small ways, for reporting purposes, for what-if analysis etc. So we have introduced Manual Adjustments. These can let you put almost anything in a completely different hierarchy. Which is fine, until you really need to find something in its expected place in the structure. Manual Adjustments allow you to defy the rules, but Structure here is to visualize these rules primarily and Manual Adjustments can defeat its purpose.
That's why we recommend not to use Manual Adjustments in structures many people use on a regular basis, but only apply them to make final touches to a report, do what-if analysis, or otherwise work with Jira hierarchy privately and occasionally. The final decision is up to the customer of course, but just a word of warning, powerful tools can let you make powerful mistakes.
In cases when you need only to change the order of your issues within a branch level, you can use Automation - Sort By>Manual Reordering. Which will not let you break hierarchy but allow you to move issues up or down a row for prioritization for example.
No promises here, Nathaniel, as Cloud API is much more restrictive than server one. We plan to implement as many features from server version into cloud as possible, but when it will happen is not a certainty.
